A Study on the Development of a Filtration System for Drainage Discharge Capacity

This study analyzes the social and economic characteristics of an area affected by chemical emission facilities and proposes policy measures to respond to social disasters such as hazardous chemical emission accidents. Even within the area affected by chemical discharge facilities, social and economic disparities existed depending on the proximity to the chemical discharge facility, child population ratio, and land value. However, the elderly population ratio decreased. It is believed that the presentation of response plans based on the study’s analysis will contribute to protecting people's health and property, which is the ultimate goal of chemical management.

A strategic brand development framework for expanding cardiovascular and endocrinology treatments in emerging markets

This paper introduces a conceptual framework for strategic brand development in the pharmaceutical industry, specifically targeting the cardiovascular and endocrinology treatment sectors in emerging markets. The framework explores how stakeholder engagement, market segmentation, and brand positioning can enhance access to critical treatments, addressing growing public health challenges in these regions. Cardiovascular and endocrinological disorders, such as heart disease and diabetes, are rising rapidly in emerging markets due to lifestyle changes, urbanization, and increased life expectancy. Pharmaceutical companies face unique challenges in expanding their market presence in these regions, including varying healthcare infrastructure, economic disparities, and regulatory environments. The proposed framework emphasizes the importance of engaging key stakeholders—such as healthcare professionals, policymakers, and patients—through targeted educational campaigns, partnerships, and advocacy. Effective stakeholder engagement fosters trust and collaboration, which is essential for expanding access to life-saving treatments. In addition, market segmentation is a critical component of this strategy, allowing companies to tailor their marketing efforts to specific demographic groups, economic conditions, and healthcare needs in each region. By identifying the most relevant segments and understanding their unique needs, companies can ensure that their treatments reach the populations most at risk for cardiovascular and endocrinological diseases. Brand positioning is another cornerstone of this framework. By clearly defining and communicating the value of their treatments in terms of efficacy, affordability, and accessibility, pharmaceutical companies can differentiate themselves in increasingly competitive markets. Strategic positioning not only enhances brand visibility but also builds long-term customer loyalty, which is crucial for sustaining market growth in emerging economies. Overall, this conceptual framework provides a roadmap for pharmaceutical companies to strategically develop their brands in the cardiovascular and endocrinology sectors, ultimately contributing to improved public health outcomes in emerging markets.

The benefits and limitations of establishing the PA profession globally: A systematic review and mixed-methods study.

Physician associates/assistants (PAs) and their equivalents offer a solution to the supply and demand crisis to alleviate global healthcare needs. This study investigated how PA and PA equivalents address global healthcare needs across different healthcare systems, revealing recommendations for their use. The study also sought to catalog the global healthcare needs that PAs and equivalents are successfully alleviating, the roles in which they function, and the barriers facing implementation. A systematic review was conducted from October 2021 to April 2022 and rerun in June 2023 following PRISMA 2020 guidelines; additionally, supporting interviews were conducted with PAs and global health experts. Primary outcomes were geographic region, economy, healthcare needs, and healthcare systems. Secondary outcomes were PA use, license recognition, and successes or barriers when implementing PAs. The literature and interviews focused on the global use of PAs and PA equivalents in six geographic regions, 63 countries, and five US territories where PAs or PA equivalents are employed, have been employed, are volunteering, or are being considered to support global healthcare needs. Most countries have a developing economy and an out-of-pocket healthcare system. PAs and PA equivalents hold 35 different practice titles, and most work in primary care. PAs alleviate healthcare shortages and economic disparities, specifically related to inequitable healthcare access. Globally, the profession is limited by a lack of legislation, regulation, and support. PAs and PA equivalents worldwide belong to an adaptable profession that has well-documented success in alleviating the global healthcare shortage and addressing healthcare needs. Countries desiring PAs or PA equivalents should identify their specific needs, train their existing workforce, employ pilot programs, and focus on seeking early legislation and regulation. Broad support for existing PA and PA equivalent international organizations is recommended for global collaboration. This study serves as a guide for those advocating for the continued or future implementation of PAs and PA equivalents in their own country and provides a comprehensive resource to aid in the globalization of this profession. We offer recommendations to address the dire healthcare needs and workforce shortage faced across the globe.

Community-based economic romance and integration: assessing the feasibility of a currency union in South Asia

Purpose This purpose of this study aims to critically evaluate the feasibility of establishing a single currency area within the South Asian Association for Regional Cooperation (SAARC) by examining the economic integration of its member states. The analysis focuses on the extent to which the region meets the criteria of the optimum currency area (OCA) theory, particularly in terms of business cycle synchronization, labor mobility and capital flows. Design/methodology/approach Using a vector autoregression (VAR) model within the aggregate demand-aggregate supply framework, this research investigates the symmetry of supply and demand shocks across SAARC economies. The study analyzes the synchronization of business cycles and the mobility of labor and capital to determine the readiness of SAARC for a unified currency. Findings The results indicate significant asymmetries in business cycles among SAARC countries, with substantial disparities in economic responses to shocks. These findings suggest that the region lacks the necessary economic synchronization required for a successful single currency area. Limited labor and capital mobility further complicate the potential for economic integration within SAARC. Research limitations/implications The study is constrained by data inconsistencies and the limited range of economic indicators available for SAARC countries. Future research should expand the analysis to include a broader set of socioeconomic factors and more comprehensive data sets to better assess the region’s potential for monetary integration. Practical implications The study highlights the challenges of forming a currency union in South Asia due to economic disparities and limited mobility. However, gradual steps toward deeper regional integration, improved financial infrastructure and enhanced cross-border collaboration could foster long-term economic stability, growth and social cohesion in the SAARC region. Social implications The research highlights the potential social benefits of enhanced economic integration, such as increased community resilience and social cohesion, while also warning of the risks associated with premature monetary union in a region with significant economic disparities. Originality/value This study provides a detailed analysis linking the theoretical framework of the OCA to the practical realities of economic integration in South Asia. By focusing on the specific economic conditions of SAARC member states, the research offers valuable insights for policymakers considering regional monetary integration.

Rural areas as winners of COVID-19, digitalization and remote working? Empirical evidence from recent internal migration in Germany

Abstract The COVID-19 pandemic has caused economic crises and increased inter-regional economic disparities. However, the catalyst effect that the pandemic has had on digitalization may change the traditional pattern of internal migration, in favour of rural areas. Using time-sensitive register data we explain changes in net migration rates of German districts from an economic geography perspective. We show that, since the beginning of the pandemic, rural regions benefited more from migration. In particular, younger and highly skilled individuals increasingly move to rural areas. This confirms that rural regions can benefit from increasing remote work, but these effects differ across region types and individual skill levels.

The cost of not getting care: income disparities in the affordability of health services across high-income countries

Abstract This presentation will present findings from the Commonwealth Fund 2023 International Health Policy Survey of the General Population, focusing on financial barriers in accessing healthcare among adults across 10 countries. It highlights significant income-related disparities in healthcare affordability, particularly in the United States, where nearly a quarter of the population lacks affordable access to care. While disparities exist in other countries, Germany and the Netherlands demonstrate lower rates of affordability issues and income disparities, possibly due to their universal health coverage models and cost-sharing caps based on income levels. These countries also prioritize mental health and dental care within their public health plans. The analysis emphasizes the critical need for affordable and comprehensive healthcare coverage to ensure equitable health outcomes. It suggests that policies such as cost-sharing caps and income-based subsidies could mitigate financial barriers to care, drawing insights from successful models in Germany and the Netherlands. Ultimately, addressing affordability is vital for achieving health equity and improving overall population health.

Increasing inequalities in mortality among individuals with a foreign background in Sweden

Abstract Background Previous research indicates that migrants in high-income destination countries not only experience a mortality advantage but also demonstrate lower or absent socioeconomic inequalities in mortality compared to the general native population. Yet the extent to which an income mortality gradient may also be evident among the descendants of migrants has been largely unexamined. Existing evidence has revealed that descendants of migrants face mortality risks higher than both migrants and their native-born peers. Methods This study utilizes longitudinal population registries covering the entire registered population of Sweden from 2004 to 2016. The study population comprises individuals aged 25 to 64, employing an open cohort design. Using Poisson regression, we examine the relationship between income rank position and cause-specific mortality among native-origin Swedes and eight nativity groups based on individuals’ country/region of birth, age of migration or parental origin. Results While foreign-born individuals who migrated as adults exhibited lower inequalities in all-cause mortality compared to native-origin Swedes, descendants of immigrants, particularly those with non-European backgrounds, show larger inequalities. Examination of specific causes of mortality revealed that external causes, notably accidents and assaults, account for increased disparities among non-European foreign-born men who migrated during childhood and male descendants of immigrants with non-European backgrounds. Conclusions Income-related inequalities in mortality are less pronounced among migrants compared to the native-born majority population in Sweden and tend to be higher among descendants of migrants, depending on gender and parental origin. The analysis highlights the role of external causes of mortality in shaping these inequalities, indicating that income disadvantages, augmented by a migrant background during upbringing, amplify specific health risks within these groups. Key messages • The study reveals lower mortality inequalities among migrant adults but a higher magnitude of inequalities among male descendants of immigrants, especially with non-European backgrounds. • Income disparities, combined with migrant backgrounds, amplify health risks among descendants of migrants in Sweden, underscoring the need for tackling social inequalities.

Does import trade liberalization worsen residents’ health? Evidence from China

Health is important to human capital and national sustainable development. Based on the latest Chinese Family Panel Studies (CFPS), this paper uses the IVprobit model to test the impact of import trade liberalization on residents’ health from the micro-individual perspective and further explores its mechanism. The results indicate that import trade liberalization brings hidden health costs, and that the negative effects on the health of people in eastern China or rural areas, people with a low education background, people under 60 years of age, and women are more significant. In areas with more serious environmental pollution, the health deterioration effect of expanding imports is more obvious. Increasing green coverage and optimizing the quality of public services can effectively alleviate this negative impact. Import trade liberalization does not affect residents’ health through income gap, therefore when carrying out import trade liberalization the government should pay greater attention to the health status of the specified groups, adopt various means to improve the ecological and living environments, reduce pollution emissions, optimize the supply of public services, and ultimately improve residents’ overall health level.

10.N. Scientific session: Gender and parenthood: short and long-term income, career, and health inequities

Abstract Despite the last decades’ changes in the distribution of household and child-rearing tasks, its main responsibility tends to fall on women. As such, parenting may remain an important determinant of gender inequalities in income, careers, and health and well-being. In 2022, on average, European women’s gross income was 12.7% below men’s. This income gap is, in part, explained by inequalities in full-time employment: in the EU, 31.5% of women with children worked part-time, which contrasts with 20.2% of women without children, with 4.9% of men with children, and 7.2% of men without children. These income and career impacts may occur due to the persistence of some traditional conceptions of the division of paid and nonpaid labor. These conceptions, and the subsequent inequalities in career progression and income, may be reflected in women’s living conditions, work-family conflict, chronic strain, well-being, and health. Yet, it can also be posited that men, experiencing the pressure to remain the main provider in the family and the most recent expectations to comply with childrearing roles, may also see their well-being and health affected. However, countries with higher gender equity have shown better results in life expectancy and healthy life expectancy for women and men. It can be argued that women and men, especially those who have children, benefit from countries with more progressive parental policies, such as longer and more equally divided parental leaves, accessible childcare, or flexible working schemes. It could, thus, be expected that these countries present higher gender equity in paid and nonpaid work division, career progression, and income, with a higher couple balance, and healthier family environments, with health gains for women and men who are parents and their children. This workshop aims to present and open to discussion recent research outcomes on the role of parenthood on income, career, and health inequalities across European countries. It will show results from quantitative and qualitative studies that focus on analyzing these impacts in the short- and long-term. By discussing these results, researchers and public health professionals may grasp parental, labor market, or social policies or health programs to foster gender equality in access to better living conditions and health, especially during and after parenthood. Key messages • Parenthood may widen gender inequities regarding income and career progression, contributing to the gender gap in health and well-being. • By understanding the magnitude of gender inequities and their distribution across countries, public health researchers and professionals may identify policies that effectively address the gender gap.

Disparities in the access to atrial fibrillation ablation in Denmark

Abstract Background Atrial fibrillation (AF) is a common arrhythmia that can lead to serious complications such as stroke, heart failure, as well as reduced quality of life. Radiofrequency and cryoablation are safe and effective treatments for AF, but they are not offered equally to all patients. Purpose The study aims to identify the demographic groups more or less likely to undergo AF ablation. Methods Using nationwide National Registries, all Danish patients with newly diagnosed AF between the 1st of January 2005, and the 31st of December 2018 were identified. The association between patients, stratified by gender, age, level of education and attachment to the job market, and the likelihood of receiving AF ablation was investigated using multivariable Cox proportional-hazard analysis. Cumulative incidence of AF ablation among these groups was calculated using the Aalen-Johansen estimator, taking death as a competing risk into account. Results A total of 176,248 patients were included in the study. Men were more likely to receive ablation than women (7% vs 3%). When analysing age, patients aged 25-44 and 45-64 were most likely to receive ablation, while only 0.7% of patients aged 80 or above received ablation. The rate of ablation significantly decreased with decreasing level of education. Patients with a Ph.D. or doctorate degree were more likely to receive ablation than patients with only basic school education (22% vs 2%). Finally full-time employed patients were most likely to receive ablation, followed by self-employed, unemployed, on sick leave, undergoing education, and early retired patients. Retired patients were the least likely to receive ablation (3%). Conclusion This study found that women, older patients, patients with lower levels of education, and patients who are not employed or who are retired are less likely to receive AF ablation. These findings suggest that there are significant social and economic disparities in AF ablation treatment in Denmark.Ablation by educationForest plot: Cox analysis

Maintaining Agricultural Production Profitability—A Simulation Approach to Wheat Market Dynamics

Profitability is a complex notion, intertwined with theoretical, socio-economic, and modern economic considerations. While traditionally linked to monopoly advantages, contemporary views broaden this to include shareholder value creation. In agriculture, profitability faces impediments such as rising input costs, market volatility, and economic disparities, emphasizing technological innovation, market conditions, and policy as crucial determinants. This study presents an econometric simulation model to analyze and forecast wheat production profitability in Poland from 2023 to 2027, providing insights into production efficiencies, market dynamics, and policy impacts. Using a system of recursive equations, the model forecasts profitability, integrating econometric techniques with expert insights. It examines variables like resource use, production levels, and price changes, validated through FADN data. The findings reveal that price relations and production efficiencies are the key to profitability. The model highlights market volatility, particularly through “price scissors”, as the main factor influencing profitability. Favorable price conditions significantly boost profitability and incentivize production. The model is a critical tool for analyzing wheat profitability, highlighting the influence of market and policy changes. Future work could extend the model’s use to other regions or crops, incorporating advanced technologies to improve accuracy. This study offers valuable insights for agricultural economics, aiding stakeholders in strategic decision-making.

Population trends and demographic disparities in sexual identity in Stockholm County, 2010 to 2021

Abstract Background Sexual identity, linked to experiences of disadvantage and discrimination, is crucial in equality monitoring. Sweden’s gender-neutral marriage laws, introduced in 2009, provide a unique context. This study examines the population trends and demographic disparities in sexual identity over time. Methods We analyzed three population surveys (2010, 2014, 2021) from the Stockholm Public Health Cohort, including around 50,000 individuals per survey. Sexual identity was assessed via self-administered questionnaires. Demographic data were sourced from Swedish national registers. Weighted multivariate Poisson regression with robust variance estimators was used to identify demographic disparities in sexual identity. Results were presented as proportion ratio (PR) with 95% confidence interval (CI). Results Overall, 29,607 (2010), 20,249 (2014), and 22,558 (2021) individuals reported sexual identity. Heterosexual identity decreased from 95.7% (95% CI 95.4-96.0%) in 2010 to 89.0% (88.5-89.4%) in 2021, while bisexual identity increased from 1.4% (1.2-1.6%) in 2010 to 2.0% (1.8-2.3%) in 2014, and further up to 2.7% (2.4-2.9%) in 2021. Homosexual identity increased slightly from 1.5% (1.4-1.7%) in 2010 to 1.8% (1.6-2.0%) in 2021. Multivariate analyses showed that female, older age, and lower education were inversely associated, while never-married status and living alone were positively associated, with homosexual identity. In contrast, female, younger age, lower income (100 SEK/year) ( < =2,500 vs > 4,500: 2010: PR 3.32 [95% CI 1.92-5.75]; 2014: 1.83 [1.28-2.60]; 2021: 1.51 [1.14-2.01]), and never-married status (never vs currently married: 2010: 2.03 [1.47-2.80]; 2014: 1.92 [1.39-2.65]; 2021: 1.50 [1.15-1.95]) were positively associated with bisexual identity. Conclusions Heterosexual identity decreased while homosexual/bisexual identities increased in Stockholm County during 2010-2021. Socioeconomic disparities persist in sexual minorities and vary by sexual identity. Key messages • Marked socioeconomic disparities persist in sexual minorities and vary by sexual identity in Stockholm County, although income and marital status disparities in bisexual group seem narrowing. • Future studies are warranted to investigate the social dynamics that continue to produce sexual minority disadvantages.

BRIDGING THE DIGITAL GAP: ANALYSING THE IMPACT OF ICT DIFFUSION ON INCOME INEQUALITY IN INDONESIA

The development of information and communication technology (ICT) has significantly transformed the socio-economic structure of society, particularly in terms of income distribution. This study aims to analyse the impact of ICT development on income inequality across 34 provinces in Indonesia from 2012 to 2020, employing econometric methods based on panel data through a fixed effects model. Empirical findings reveal that ICT readiness and ICT skills tend to exacerbate income inequality, while ICT use and its quadratic form contribute to reducing it. These results suggest that although ICT infrastructure and skills are crucial, their uneven distribution and utilisation can widen income disparities. Consequently, this study highlights the importance of ensuring equitable access to ICT across Indonesia to mitigate economic inequality. The study's recommendations stress the pivotal role of the government in expanding ICT infrastructure, fostering a research and innovation climate conducive to digital transformation, and formulating policies that enhance ICT skills nationwide. These measures would improve digital literacy, upgrade workforce capabilities, and promote inclusive digital economic growth. Ultimately, comprehensive and equitable ICT development can play a critical role in reducing income inequality across Indonesia.

Does the Adjustment of Industrial Structure Restrain the Income Gap between Urban and Rural Areas

Abstract Industrial structure adjustment is a process that involves reconfiguring input factors to enhance productivity and efficiency. A crucial aspect of this adjustment is the transformation of the labor force composition, which subsequently affects the employment structure. Consequently, variations in productivity levels lead to the cross-departmental migration of workers, resulting in changes to the income disparities among employees. This article examines the impact of China’s industrial structure adjustment and labor mobility on the urban–rural income gap between 1990 and 2019. Employing an empirical approach, the study investigates the influence of industrial structure adjustment and the direction of labor mobility on the urban–rural income gap. The findings indicate that the quality of industrial structure adjustment contributes to the widening of the urban–rural income gap, whereas labor mobility helps to narrow it. In regions experiencing a net influx of labor, superior industrial structure adjustment amplifies the urban–rural income gap, whereas labor migration diminishes it. Conversely, in regions witnessing a net outflow of labor, superior industrial structure adjustment reduces the income gap, while labor mobility widens the urban–rural income disparity. Notably, in more developed areas of China, the quality of industrial structure adjustment has widened the income gap, whereas labor mobility has narrowed the urban–rural income gap. However, in less developed regions, labor mobility exacerbates the urban–rural income gap.

Quantitative evidence of the community of shared future for mankind as a driver of sustainable development in human society

In an era marked by global economic challenges, an increasing array of non-traditional security threats, and a proliferation of conflicts and issues, China has put forth the building of a community of shared future for mankind as a way to address this question of the times. The theory of the community of shared future for mankind offers a framework to address contemporary issues by promoting equality, mutual benefit, security, justice, openness, innovation, multicultural exchange, and green development. This paper innovatively quantifies the five core principles of the theory of the community of shared future for mankind using the entropy method. It calculates the proxy variable for sustainable development, green total factor productivity, using the super-efficiency Slack-Based Measure model in Data Envelopment Analysis. Baseline regression is conducted on this basis. The Principal Component Analysis method and another Data Envelopment Analysis method, the Malmquist index, are utilized to recalculate the indicators, followed by another round of regression analysis. The results are consistent with the baseline regression. Additionally, Ordinary Least Squares, Partial Least Squares, Maximum Likelihood Estimation, Ridge regression, and Lasso regression are employed to ensure the robustness of the results. The findings indicate a significant positive relationship between the community of a shared future for mankind and the sustainable development of human society, with consistent conclusions drawn from different calculation methods and regression techniques. Through value recognition, international cooperation based on benefit-sharing and mutual reciprocity can guide humanity towards a harmonious coexistence with nature, irrespective of regional and economic disparities. This study provides quantitative evidence of the impact of the community of a shared future for mankind on the sustainable development of human society, filling a gap in existing research. Based on these findings, feasible policy recommendations are proposed to promote sustainable development in human society.

Analysis of Factors Affecting the Spatial Association Network of Food Security Level in China

Food security serves as the cornerstone of national security, intricately linked to social stability and economic progress. Currently, with the swift evolutions in social economy, logistics and transport, information dissemination, and technological advancements, there has been a marked increase in the cross-regional flow of food production, distribution, and consumption. Consequently, the spatial interdependence of food security across different regions has grown increasingly salient. This paper investigates the spatial interrelationship of food security levels in China through a network analysis framework, examining its determinants and network dynamics. The findings offer valuable insights for decision-makers aiming to optimize agricultural resource allocation and enhance national food security levels. This research establishes a comprehensive evaluation index system for assessing food security levels in China across four dimensions: production security, distribution security, supply security, and consumption security. Employing data from 30 provinces between 2008 and 2022, the entropy method quantifies food security levels, while a modified gravity model underpins the construction of a spatial association network. This framework subsequently examines the network’s structural characteristics and the factors influencing its formation. The results reveal that: (1) China’s food security levels demonstrate a consistent upward trajectory over the study period, though significant regional disparities persist. The central region surpasses the national average, while the eastern and western regions lag. Recently, the western region has shown accelerated improvements in food security, followed by the central area, with the eastern region maintaining steady growth. (2) A structurally robust spatial correlation network of food security has emerged, characterized by variations in the number of network relationships, fluctuations in network density, and a decline in network efficiency while still exhibiting pronounced small-world characteristics. (3) The network displays a clear core-periphery structure, with Shanghai, Beijing, and Jiangsu positioned centrally, playing pivotal intermediary roles, whereas remote provinces such as Gansu, Ningxia, and Liaoning occupy the periphery. (4) The four major regions demonstrate sparse internal connectivity yet robust inter-regional ties, resulting in pronounced spillover effects. (5) Various factors, including geographic distance, provincial proximity, disparities in economic development levels, variations in marketization, differences in agricultural human capital, and disparities in land productivity, significantly impact the establishment of spatial correlations in food security. The affirmative influences of geographic distance and neighboring relations, along with the beneficial shifts in economic development disparities, suggest that the flow of technology and resources plays a crucial role in reinforcing spatial connections.

Environmental justice of Texas recreational water quality – The disproportionate E. coli levels and trends

The presence of pathogens is one of the leading causes of stream water quality impairment in the US. Escherichia coli (E. coli) is a fecal pathogen indicator and also signals the presence of more pathogenic microbes. Although it is reported that Black, Indigenous, and communities of color suffer more from E. coli contamination, there is a lack of investigation of the potential inequality of E. coli contamination in recreational waterbodies, particularly regarding whether this inequality persists over the long term. Using E. coli monitoring data from 1,424 stations from 2001 to 2021 in Texas, we tested the research hypotheses of racial and economic inequalities in E. coli levels and trends with quantile regression and logistic regression approaches. We found that economic disparities had a more significant relationship with E. coli contamination in Texas recreational waterbodies than racial disparities after controlling for building age, land covers, imperviousness, and precipitation. The economic disparities in E. coli contamination were more prevalent after 2010 and in extreme E. coli levels. In addition, implementing watershed protection plans could mitigate the economic disparities associated with the rising trend of E. coli levels between 2001 and 2021. Findings from this research underscore clean surface water deprivation from underserved communities and call for inclusive watershed management strategies to address the water quality injustice.

Assessing Regional Economic Performance in Romania Through Panel ARDL and Panel Quantile Regression Models

This study aims to address the persistent regional economic disparities in Romania by evaluating economic performance through Panel Autoregressive Distributed Lag (pARDL) and panel quantile regression (PQR) models. The analysis focuses on the impact of key economic variables, including research and development expenditures (CTCRD), IT infrastructures (IT), the number of universities (FCL), and the average number of employees (NMSP), on regional gross domestic product (GDPR). Using data from the Romanian National Institute of Statistics for the period 2003–2022, this research seeks to understand how targeted investments and policy interventions can stimulate growth and reduce inequalities across regions. The findings highlight the important role of R&D, IT infrastructures, and technological advancements in driving economic growth, especially in less developed areas. The study also emphasizes the importance of region-specific strategies in fostering sustainable growth, promoting economic resilience, and bridging the gap between more and less prosperous regions.

Research on the Influence of Digital Economy on the Income Gap between Urban and Rural Areas in China

In recent years, with the rapid advancement of information technology and the widespread proliferation of the Internet, digital technology has been reshaping the value chains of traditional industries and giving rise to entirely new business models and industrial forms. Technologies such as the Internet, big data, and artificial intelligence are being applied across various sectors, while new formats like e-commerce, the sharing economy, and online education are flourishing. These developments have driven new consumption patterns and employment methods. The rapid rise of the digital economy not only boosts production efficiency and economic growth but also influences the income distribution between urban and rural areas to some extent. This paper begins by examining the current state and characteristics of the digital economy and then analyzes its impact on the urban-rural income gap. Additionally, it offers countermeasures and recommendations for narrowing this gap, providing theoretical support for promoting common prosperity.

Effects of economic growth target on the urban–rural income gap in China: An empirical study based on the urban bias theory

Urban–rural imbalance is a common phenomenon, and its prominent manifestation is the sustained expansion of the urban–rural income gap. For emerging countries, this gap encountered during the development process should be addressed by promoting development, which also puts forward high requirements for economic management. Inspired by political economy theory and the widening urban–rural income gap in China, this study constructs a theoretical framework of “purpose-behavior-performance-structure” based on the urban bias theory, and then quantitatively examines the effect of economic growth target on the urban–rural income gap based on panel data at the provincial level. In addition, we explore the mechanism by which economic growth targets affect the urban–rural income gap with the mediating effect model, and investigate the impact of marketization and spatial structure on the relationship between economic growth targets and urban–rural income gap with the moderating effect model. The results show that the economic growth target significantly contributes to the widening urban–rural income gap in the face of the political promotion incentives and economic growth target accountability system, and this effect exhibits substantial spatiotemporal heterogeneity. In addition, fiscal expenditure, fixed asset investment, and labor mismatch under urban bias are important mechanisms that lead to the widening urban–rural income gap, and the marketization level and spatial structure significantly affect this relationship. We put economic growth management, urban bias, and urban–rural income gap into the “purpose-behavior-performance-structure” theoretical framework, which provides a new explanatory perspective for understanding the urban–rural income gap in emerging economies, and new policy insights for rational economic growth management.
