Directional nature of technological progress in the petrochemical industry prompting energy marginal substitution

Technological progress does not uniformly benefit all industries or factors' productivity levels. The energy productivity and labour employment situation in the Chinese petrochemical industry have not witnessed substantial improvements in the last decade. The literature has overlooked the importance of recognizing the directional nature of technological progress, which could enable a more strategic approach to economic development, resource allocation, and policy formulation. This study, guided by the core principles of endogenous economic growth theory, aims to uncover the influencing mechanisms and effects of technological progress bias on energy and employment by extending a theoretical model to account for energy, capital, and labour factors. The results reveal: (1) From 2000 to 2021, the relationship between labour, capital, and energy factors in the Chinese petrochemical industry has been predominantly complementary, with technological progress favouring labour-augmenting that is increasing labour productivity; (2) The gross complementarity of production factors leads to labour-augmenting technological progress, ultimately biased towards energy and capital factors; (3) Energy-capital-biased technological progress encourages producers to invest more energy and capital to substitute for labour factors, leading to a limited improvement in energy productivity and a consistent decline in labour employment since 2011. This study further corroborates that without government intervention, it would lead to improper factor allocation in the industry, resulting in market failure. Finally, corresponding policy recommendations are proposed.

Endogenous phytohormone analysis during sequential stages of somatic embryogenesis in Musa AAA cv. Grand Naine (subgroup Cavendish)

Abstract This is the first initiative study to provide quantified levels of four endogenous phytohormones during the induction, regeneration, maturation and germination stages of somatic embryogenesis (SE) in banana, using immature male bud explants, in the popular commercial triploid cultivar Grand Naine (AAA). Phytohormones are known to play a major role in the regulation of SE and most protocols have been developed for various cultivars of banana following empirical approaches. Although, several reports are available with regard to the impact of growth regulators exogenously supplemented to the media, the vital role of endogenous growth hormones in various developmental stages of SE remain unclear in banana. Reverse Phase High Performance Liquid Chromatography (RP-HPLC) was used to analyze endogenous status of indole acetic acid (IAA), zeatin, gibberellic acid (GA) and abscisic acid (ABA). Results from this study revealed that endogenous IAA and GA along with exogenous auxin play a major role in the induction of embryogenic competence of male bud explants. The levels of endogenous IAA and zeatin were found to be higher in embryogenic calli than non-embryogenic calli, although three different types of exogenous auxins were supplemented in callogenesis medium, but not cytokinin. Higher level of ABA and GA was observed in early and late developmental stages of somatic embryo, respectively. GA also played a predominant role in germination of somatic embryos. These findings will be applied for improvement of SE protocol in recalcitrant banana cultivars by suitably altering or supplementing exogenous growth hormones.

Market Regulation, Cycles, and Growth Dynamics in a Monetary Union

AbstractWe build a two‐country currency union dynamic stochastic general equilibrium (DSGE) model with endogenous growth to assess the role of product market regulation (PMR) and labor market regulation (LMR) for growth and the adjustment to shocks. We show that with endogenous growth, there is no reason to expect real income convergence. Large shocks can lead to permanent changes of output and real exchange rates. Differences are exacerbated by different PMR and LMR. Less regulated economies have higher trend growth and recover faster from negative shocks. Results are consistent with higher inflation, lower employment, and disappointing total factor productivity (TFP) growth rates experienced in more regulated euro area members.

Unravelling the secrets of soil microbiome and climate change for sustainable agroecosystems.

The soil microbiota exhibits an important function in the ecosystem, and its response to climate change is of paramount importance for sustainable agroecosystems. The macronutrients, micronutrients, and additional constituents vital for the growth of plants are cycled biogeochemically under the regulation of the soil microbiome. Identifying and forecasting the effect of climate change on soil microbiomes and ecosystem services is the need of the hour to address one of the biggest global challenges of the present time. The impact of climate change on the structure and function of the soil microbiota is a major concern, explained by one or more sustainability factors around resilience, reluctance, and rework. However, the past research has revealed that microbial interventions have the potential to regenerate soils and improve crop resilience to climate change factors. The methods used therein include using soil microbes' innate capacity for carbon sequestration, rhizomediation, bio-fertilization, enzyme-mediated breakdown, phyto-stimulation, biocontrol of plant pathogens, antibiosis, inducing the antioxidative defense pathways, induced systemic resistance response (ISR), and releasing volatile organic compounds (VOCs) in the host plant. Microbial phytohormones have a major role in altering root shape in response to exposure to drought, salt, severe temperatures, and heavy metal toxicity and also have an impact on the metabolism of endogenous growth regulators in plant tissue. However, shelf life due to the short lifespan and storage time of microbial formulations is still a major challenge, and efforts should be made to evaluate their effectiveness in crop growth based on climate change. This review focuses on the influence of climate change on soil physico-chemical status, climate change adaptation by the soil microbiome, and its future implications.

Evaluation of Public Sector Corruption and Organized Crimes as Impediments to Nigeria’s Economic Growth

This research work on the evaluation of public sector corruption and organized crime as an impediment to Nigeria’s economic growth attempts to examine the link between crime and growth based on the theory of rational choice and empirical data.the major objective of this research is to evaluate the extent to which public sector corruption and organized crime impacted on economic growth in Nigeria. The Dynamic Endogenous Growth model is adopted to analyse the data collected as the study sought to cast further light on the macroeconomic implications of organized crime and its interaction with corruption. The study concludes that to eradicate organized crime and corruption in Nigeria, effort should be geared towards a fool-proof, digitized intelligence gathering on identifying the roots causes and a way to nip them in the bud. All leakages in the public sector also need to be blocked to curtail loopholes for corruption to thrive It is recommended that prosecution be forcefully pursued through the enactment of an accountability legislation for public office holders and the enhancement of police and court system skills through sufficient funding.Furthermore, the government ought to take action to promote a more productive economy, which would lower unemployment and serve as a deterrent to crime.

Effectiveness of the modified WHO labour care guide to detect prolonged and obstructed labour among women admitted at publicly funded facilities in rural Mbarara district, Southwestern Uganda: an ambispective cohort study.

Obstructed labour, a sequel of prolonged labour, remains a significant contributor to maternal and perinatal deaths in low- and middle-income countries. We evaluated the modified World Health Organization (WHO) Labour Care Guide (LCG) in detecting prolonged and or obstructed labour, and other delivery outcomes compared with a traditional partograph at publicly-funded maternity centers of rural Mbarara district and City, Southwestern Uganda. Since November 2023, we deployed the LCG for use in monitoring labour by trained healthcare providers across all maternity centers in Mbarara district/City. We systematically randomized a total of six health center IIIs (HCIIIs) out of 11, and all health center IVs (HCIVs), reviewed all their patient labour monitoring records for their first quarter of 2024 (LCG-intervention) and 2023 (partograph-before LCG introduction). Our primary outcome was the proportion of women diagnosed with prolonged and or obstructed labour. Our secondary outcomes included; tool completion, mode of delivery, labour augmentation, stillbirths, maternal deaths, Apgar score, uterine rupture, postpartum haemorrhage (PPH). Data was collected in RedCap and analyzed using STATA version 17. Statistical significance was considered at p<0.05. A total of 2,011 women were registered; 991 (49.3%) monitored using the LCG, and 1,020 (50.7%) using a partograph, 87% (1,741/2011) delivered from HCIVs and 270/2011 (13%) from HCIIIs. Mean maternal age (25.9; SD=5.6) and mean gestation age (39.4; SD=1.8) were similar between the two groups. A total of 120 (12.4%) cases of prolonged/obstructed labour were diagnosed (100 for LCG versus 20 for partograph), with the LCG having six times higher odds to detect/diagnose prolonged/obstructed labour compared to the partograph (aOR=5.94; CI 95% 3.63-9.73, P<0.001). Detection of obstructed labour alone increased to 12-fold with the LCG compared to the partograph (aOR=11.74; CI 95% 3.55-38.74, P<0.001). We also observed increased Caesarean section rates (aOR=6.12; CI 4.32-8.67, P<0.001), augmentation of labour (aOR=3.11; CI 95% 1.81-5.35, P<0.001), and better Apgar Score at 5 minutes (aOR=2.29; CI 95% 1.11-5.77, P=0.025). The tool completion rate was better for LCG compared to (58.5% versus 46.3%), aOR=2.11; CI 95% 1.08-5.44, P<0.001. We observed no differences in stillbirths, maternal deaths, post-partum haemorrhage (PPH) and uterine rupture. Our data shows that LCG diagnosed more cases of prolonged and or obstructed labour compared to the partograph among women delivering at rural publicly funded facilities in Mbarara city/district. We also observed increased C-sections, labour augmentation, and 5-minute Apgar scores. There were no differences in stillbirths, maternal deaths, PPH and uterine rupture. More controlled and powered studies should evaluate the two tools for other delivery outcomes, in different sub-populations.Trial registration number NCT05979194 clinical trials.gov.

A Lucas island model to analyse labour movement choice between cities based on personal characteristics

The labour movement has been a key factor for cities’ development and caused regional inequality between cities. Although empirical studies have been conducted to investigate it, little theoretical evidence has been provided to find out the underlying mechanism. This paper describes and derives a Lucas-Prescott style island model to study the location choices of the heterogeneous agents by utilising endogenous technology growth, which in turn influences personal human capital growth. It leads to the U-shape curve of the inequality of wage income with the technology of these islands but not in terms of total income. In the extended two-goods model, the magnitude of the implications is increased by the impact of non-tradable goods price. Together with empirical research using the US census data, this paper finds that skilled labours with less endowed wealth tend to live in large cities for its high salary. On the other hand, those less-skilled but with more endowed wealth tend to live in cities with better environment, which drives up the price level of non-tradable goods in these cities. This explains the population concentration in the super cities and the high housing price-wage ratio in some beautiful cities, which provides theoretical basement for further empirical studies about labour movement in other cities

China's economic growth and low-carbon development under the background of resource curse: A new perspective based on digital finance

Does digital finance (DIF) in the digital age mitigate the economic challenges stemming from the resource curse and facilitate low-carbon development? This paper extends the theoretical framework of endogenous economic growth to investigate the interactive relationship among economic growth, low-carbon development, and the resource curse. Furthermore, it explores the pivotal role of DIF within this context. Subsequently, this paper employs Chinese provincial data from 2011 to 2020 to empirically examine the theoretical assumptions through econometric methods. The findings are as follows. First, DIF has the potential to stimulate economic growth, whereas resource endowment can impede it. Second, DIF significantly reduces carbon emission intensity (CEI); however, a high degree of resource endowment does not foster low-carbon development. Third, in the mechanism by which resource endowment influences economic growth, DIF exhibits a single threshold effect. When the DIF level surpasses 361.46, the negative relationship between resource endowment and economic growth shifts to a significant positive correlation. Regarding the mechanisms by which resource endowment impacts CEI, DIF shows a double-threshold effect. When DIF surpasses the second threshold, the significant positive impact of resource endowment on CEI becomes significantly negative. Fourth, DIF and resource endowment indirectly influence CEI through economic development. Fifth, the impact of DIF on CEI and the influence of resource endowment on economic growth are marked by resource endowment heterogeneity. DIF exhibits a double-threshold effect on the influence of resource endowment on economic growth in non-resource endowment regions. In resource-rich areas, as the DIF level rises, the significant positive effect of resource endowment on CEI intensifies. Conversely, in non-resource endowment regions, as the DIF level increases, the significant positive effect of resource endowment on CEI transforms into a significant negative effect.

The Risk Factors of Postpartum Urinary Retention for Women by Vaginal Birth: A Systematic Review and Meta-Analysis.

Postpartum urinary retention is one of the most common complications in women during the immediate postpartum period. The objective was to systematically assess risk factors for postpartum urinary retention after vaginal delivery. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses, we retrieved relevant studies from PubMed, Embase, Cochrane Library, Web of Science Core Collection, China National Knowledge Internet, Wangfang Database, and Chinese Biomedical Database for observational studies investigating the risk factors for postpartum urinary retention from inception to 11 November 2022. The Newcastle-Ottawa Scale and Joanna Briggs Institute's tool were used to assess the risk of bias. We conducted a meta-analysis using RevMan 5.3. In total, 3,074 articles were screened and data from 27 studies were used in the meta-analysis. Sixteen risk factors were identified, namely, labor augmentation (OR = 1.72, 95% CI = 1.17-2.51), primiparity (OR = 2.36, 95% CI = 1.64-3.38), manual fundal pressure (OR = 2.84, 95% CI = 1.00-8.11), perineal hematoma (OR = 7.28, 95% CI = 1.62-32.72), vulvar edema (OR = 7.99, 95% CI = 5.50-11.63), the total duration of labor (MD = 90.10, 95% CI = 49.11-131.08), the duration of the first stage of labor (MD = 33.97, 95% CI = 10.28-57.65), the duration of the second stage of labor (MD = 14.92, 95% CI = 11.79-18.05), the duration of the second stage of labor > 60min (OR = 3.18, 95% CI = 1.32-7.67), mediolateral episiotomy (OR = 3.65, 95% CI = 1.70-7.83), severe perineal tear (OR = 3.21, 95% CI = 1.84-5.61), epidural analgesia (OR = 3.23, 95% CI = 1.50-6.96), forceps delivery (OR = 4.95, 95% CI = 2.88-8.51), vacuum delivery (OR = 2.44, 95% CI = 1.30-4.58), neonatal birth weight > 4,000g (OR = 3.61, 95% CI = 1.96-6.65), and neonatal birth weight > 3,500g (OR = 1.89, 95% CI = 1.12-3.19). Our results demonstrated that labor augmentation, primiparity, manual fundal pressure, perineal hematoma, vulvar edema, the total duration of labor, the duration of the first stage of labor, the duration of the second stage of labor, the duration of the second stage of labor > 60min, mediolateral episiotomy, severe perineal tear, epidural analgesia, forceps delivery, vacuum delivery, and neonatal birth weight > 4,000g and > 3,500g were risk factors for postpartum urinary retention in women with vaginal delivery. The specific ranges of the first and the second stages of labor causing postpartum urinary retention need to be clarified.

Endogenous Growth and Environmental Kuznets Curve: Lessons from FDI Impact on Economic Growth in Sub-Saharan Africa

Purpose: This study aims to determine the influence of Foreign Direct Investments (FDI) on economic growth in Sub-Saharan Africa (SSA). It examines the endogenous growth theory and the Environmental Kuznets Curve (EKC) theory, and how they relate to the regional data.Method: Using panel quantile autoregression models, this study explores the relationship between FDI inflows into SSA with energy consumption, carbon emissions, and economic growth. The study is based on data from 1975 to 2018.Result: The study findings conclusively demonstrate that foreign direct investment has a significant impact on the economic growth of the SSA region. Furthermore, the study reveals that energy consumption and carbon emissions in the SSA have consistently increased throughout the study period, with foreign direct investment being identified as the primary driver of this trend. These findings are consistent with the Environmental Kuznets Curve (EKC) hypothesis, as well as the endogenous growth theory, which suggests that FDI operations can have negative consequences on the host environment.Practical Implications for Economic Growth and Development: The study suggests that Sub-Saharan Africa should manage FDI carefully to balance economic growth with environmental sustainability by promoting green investments and creating an investment-friendly environment.

Green investments and inclusive growth: The case of the BRICS economies

Investments in green energy projects are highly critical to promoting climate transition and sustainable development. This objective motivates the investigation of the effect of green investments on inclusive growth. We develop an endogenous inclusive growth model that illustrates the channel through which private and public investments in green investments contribute to inclusive growth. By employing a dataset of the BRICS economies from 1990 to 2019, we fit both linear fixed-effects and fixed-effects threshold regression, the latter of which exhibits better prediction of green investment effects. Accordingly, the threshold regression estimates reveal that higher thresholds of green investments substantially accelerate inclusive growth in the BRICS economies. Furthermore, by controlling for the threshold role of financial sector development, we document the heterogeneous effects of green investments on inclusive growth. Unlike financial institutions’ development thresholds, a higher level of overall financial development and financial market development strengthens the positive role of green investments. Our findings offer impeccable policy actions to the governments and policymakers of the BRICS economies on pathways to promote green energy investments for sustainable development.

Impact Of Foreign Direct Investment On Domestic Investment In Brazil

In an era marked by rapid globalization and intricate economic interconnections, FDI has emerged as a critical driver of economic growth in many developing nations. Brazil, as the largest economy in Latin America, has witnessed significant fluctuations in FDI inflows over the past decades. The question of whether FDI can stimulate domestic investment remains a topic of considerable interest among economists, policymakers, and scholars. This study delves into the complex relationship between FDI and domestic investment in Brazil, employing historical data, economic indicators, and existing scholarly research. Brazil, as a prominent emerging economy and a global economic force, has consistently attracted international investors and governments. The nexus between economic development and FDI has garnered global attention. FDI not only involves the allocation of financial resources from foreign entities but also entails technology transfer, managerial expertise, and access to international markets. While these inflows have the potential to stimulate local investment, economic growth, and job creation, concerns exist regarding their possible displacement or crowding-out effect on domestic investments. Understanding the intricate correlation between FDI and domestic investment in Brazil is of paramount importance, shaping investment policies within the country and offering valuable insights for other emerging economies seeking to strike a balance between foreign and domestic capital. This study examines the impact of FDI on domestic investment in Brazil, analyzing historical data, economic indicators, and existing literature to provide a comprehensive understanding of this complex relationship. The research draws on economic theories such as the neoclassical growth hypothesis, endogenous growth theory, and crowding-out hypothesis to explore the potential effects of FDI on domestic investment. It considers the regional disparities in FDI distribution and the sector-specific impacts of FDI in Brazil. Additionally, the study evaluates the role of government policies, trade openness, and financial development in moderating the relationship between FDI and domestic investment. Ultimately, this research aims to shed light on the multifaceted dynamics between FDI and domestic investment in Brazil. By addressing the positive and negative aspects of this relationship, it seeks to provide valuable insights for policymakers, economists, and businesses not only in the Brazilian context but also for other nations navigating the challenges and opportunities of FDI. The findings contribute to the global discourse on the impact of FDI on a nation's economic trajectory and offer guidance for informed policy decisions.

Socio-Economic Factors Influencing Growth of Small and Medium Enterprises in Mombasa County, Kenya

Small and Medium Enterprises (SMEs) contribute over 70% of jobs, contribute to GDP, aid industrial development, satisfy local demand for services, innovate and support large firms with inputs and services. However, the SMEs in Mombasa County are constantly faced with the threat of failure where three out five fails at infancy. The study investigated the influence of economic factors (taxation, finance access and wages and unemployment) on growth of SMEs in Kenya, in Mombasa County. The specific objectives of the study were; to explore the effect of taxation on growth of SMEs, to find out the effect of Financial Access on growth of SMEs, to determine the effect of wages on growth of SMEs operating, and to evaluate the effect of general unemployment on growth of SMEs operating in Mombasa County. This study employed the institutional theory of growth, the Schumpeter theory of growth and the Endogenous growth theory anchored the study. An explanatory research design was used so as to meet the research objectives. The target population was 54,245 registered SMEs and a sample size of 246 was derived using the Cochran, statistical formula. The list of registered SMEs in Mombasa formed the study population. A Systematic Random Sampling was used from a sample of 246 SMEs was drawn. Data was collected using a structured questionnaire. Multiple regression Analysis technique was the main technique to find the effect of social economic factors on SME growth. to analyze the data using the Statistical Package for Social Sciences with a significance level set at 0.05. Findings showed that SE conditions are just modest level. Correlation results showed that Taxation conditions (r=.344, p=.000), Financial Access (r=.430, p=.000), Wages affordability (r=.241, p=.000) are positively and significantly correlated with SME growth. Regression results showed that SE factors; Taxation conditions (=.268, p=.000), Financial Access ( =.383, p=.000), Wages ( =.182, p=.015) and Unemployment ( = -.170, p=.045) has significance effect on SMEs growth. Conclusions; Socioeconomic can reverse the current trend of high SMEs failure rate. Socioeconomic factors can buck the present trend of a high failure rate among SMEs. The study recommended that the county and national governments should implement measures enhancing tax benefits for SMEs such as utilizing the taxes prudently. Additionally, the SMEs should adopt strategies that enhance internal financial capabilities so as to incase their revenue streams. Moreover, it is recommended the SMEs to have a working and sustainable wage policy that is able to attracts and keeps talented workforce and therefore ensure continued business growth. By using a multi-sectoral approach, both local and national governments should prioritize and focus on short- and long-term policies that lower the rising rates of unemployment.

Temporalities of oxytocin for labour augmentation: a mixed-methods study of time factors shaping labour practices in a busy maternity unit in Tanzania

BackgroundHigh rates of labour augmentation with oxytocin have been found in some low- and lower-middle-income countries, causing potential perinatal harm. It is critical to understand the reasons for this overuse. Aim was to explore factors that shape practices around using oxytocin for labour augmentation in a high-volume labour ward in Dar es Salaam, Tanzania.MethodsMixed-methods data collection was conducted from March 2021 to February 2022, including structured observations of 234 births, 220 h of unstructured labour ward observations and 13 individual in-depth interviews with birth attendants. Thematic network analysis and descriptive statistics were used to analyse data. We used a time-lens to understand practices of oxytocin for labour augmentation in time-pressured labour wards.ResultsBirth attendants constantly had to prioritise certain care practices over others in response to time pressure. This led to overuse of oxytocin for augmentation to ensure faster labour progression and decongestion of the, often overburdened, ward. Simultaneously, birth attendants had little time to monitor foetal and maternal condition. Surprisingly, while oxytocin was used in 146 out of 234 (62.4%) structured labour observations, only 9/234 (4.2%) women had active labour lasting more than 12 h. Correspondingly, 21/48 (43.8%) women who were augmented with oxytocin in the first stage of labour had uncomplicated labour progression at the start of augmentation. While the partograph was often not used for decision-making, timing of starting oxytocin often correlated with natural cycles of ward-rounds and shift-turnovers instead of individual women’s labour progression. This resulted in co-existence of ‘too early’ and ‘too late’ use of oxytocin. Liberal use of oxytocin for labour augmentation was facilitated by an underlying fear of prolonged labour and low alertness of oxytocin-related risks.ConclusionsTime scarcity in the labour ward often made birth attendants deviate from clinical guidelines for labour augmentation with oxytocin. Efforts to navigate time pressure resulted in too many women with uncomplicated labour progression receiving oxytocin with little monitoring of labour. Fear of prolonged labour and low alertness to oxytocin-mediated risks were crucial drivers. These findings call for research into safety and benefits of oxytocin in low-resource settings and interventions to address congestion in labour wards to prevent using oxytocin as a time-management tool.

The endogenous growth and asset prices nexus revisited with closed-form solution

Endogenous growth models exhibit long-run risks, which are considered a potential explanation of the equity premium puzzle. Unlike previous literature, we use a closed-form solution of a simplified model to make the following contributions. First, we derive a set of conditions for a positive and large equity premium. Second, we match a key driver of endogenous growth, the R&D spending-to-GDP ratio. Third, we include a novel discussion on the role of patent obsolescence. Given that the literature concerns the accuracy of loglinear-lognormal solutions, we solve our model numerically with third-order perturbation. We find additional risk correction due to higher-order terms.

Impact of Immigration Policies on Economic Growth in Germany

Purpose: To aim of the study was to analyze the impact of immigration policies on economic growth in Germany. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Germany's immigration policies have had a significant impact on its economic growth. These policies have facilitated the influx of skilled labor, which has helped to address the country's demographic challenges, particularly the aging population and labor shortages in key sectors. Immigrants have contributed to the labor market by filling both high-skilled and low-skilled jobs, boosting productivity and innovation. Additionally, immigration has increased consumer demand, further stimulating economic growth. Unique Contribution to Theory, Practice and Policy: Human capital theory, dual labor market theory &amp; endogenous growth theory may be used to anchor future studies on the impact of immigration policies on economic growth in Germany. Implement comprehensive language and vocational training programs for refugees and low-skilled immigrants to facilitate their economic integration and productivity. Formulate balanced immigration policies that address sector-specific labor demands without disadvantaging native workers.

Do regional tax incentive policies improve productivity?

The difficulty in transforming old industrial areas constitutes a significant factor contributing to regional development imbalances. Can regional tax incentives, as a crucial component of regional policies, polish the "rust belt" regions? This study leverages the inaugural Value-Added Tax (VAT) reform in China as an opportunity to explore the potential of regional tax incentives in achieving sustainable development in traditional industrial areas. Drawing upon a comprehensive industrial enterprise database, we employ a Propensity Score Matching-Difference in Differences (PSM-DID) approach to examine the efficacy of these tax incentives. Our findings reveal that: (1) Regional tax incentives primarily enhance firms productivity by stimulating investment in enterprises, yet they do not contribute to improved investment efficiency or spur innovation within firms. (2) Regional tax incentives have alleviated financing constraints for enterprises in old industrial bases, significantly enhancing the Total Factor Productivity (TFP) of firms with higher financing constraints. This policy has had an even stronger impact on improving the TFP of state-owned and monopolistic enterprises. (3) Regional tax incentives have impeded productivity growth by preventing the exit of low-efficiency firms and the entry of high-efficiency ones. These incentives also increased the likelihood of "zombie firms" forming and failed to promote endogenous economic growth in the Northeast region. Additionally, they have distorted the allocation of resources towards capital and technology-intensive industries in that area. In China's old industrial bases, regional tax incentives should be coordinated with market-oriented reforms; these regional tax incentive policies should also be further enriched.

Innovation and economic growth: An empirical analysis for African countries

In recent decades, innovation has become recognized as a key driver of economic growth. This study investigated the relationship between innovation and economic growth in 32 African countries from 2006 to 2017. The linear regression panel corrected standard errors (PCSEs) regression estimation was used to analyze the data. PCSE estimation accounted for heteroskedasticity and possible contemporaneous correlation across panels. The findings showed a positive association between the innovation index and economic growth. This result remained true even when research and development (R&D) expenditure (the conventional measure of innovation) was considered for a handful of countries. This finding highlights the significance of innovation in fostering economic growth. The study also found that domestic investment and human capital encouraged economic growth. The study estimated an endogenous growth model with an alternative measure of innovation. Based on the findings, the study recommends that African countries provide financial and material support for R&D in public and private institutions through funding, imparting entrepreneurial research attitudes in academics, and providing an enabling environment for business enterprises.

ICT diffusion, E-governance, and sustainability in the digital era

This study analyses the impact of information and communications technology (ICT) diffusion and e-governance on sustainability in 148 Belt and Road Initiative (BRI) partner countries. It considers control variables such as institutional quality, urbanization, research and development (R&D), and the COVID-19 effect as dummy variables. Two step-generalised method of moments analysis of a panel dataset of 148 BRI partner countries from 2013 to 2021 reveals that ICT diffusion and e-governance benefit sustainability, with R&D and institutional quality also making positive contributions, while urbanization and the pandemic negatively impact sustainability. The findings were validated through D-K regression checks and support the technology spill-over effect, innovation, triple bottom line, endogenous growth, and stakeholder theories. They highlight the significance of investing in ICT infrastructure and digital literacy programs, improving institutional reforms and governance practices, putting sustainable urban planning into practice, and supporting R&D projects to advance sustainability in BRI partner nations. This study clarifies the potential problems brought forth by the pandemic and makes suggestions for reducing its negative effects on sustainability. It contributes to evidence-based decision-making, guiding sustainable practices in BRI partner nations.
