Research on the driving effect of marine economy on the high-quality development of regional economy – Evidence from China’s coastal areas

Exploring the driving effect of the marine economy on high-quality economic development can help improve the quality of national economic development and optimize the direction of marine economic development. Based on the data of China’s coastal areas from 2006 to 2019, this study adopts the entropy weight-TOPSIS method to comprehensively evaluate the level of marine economy and the high-quality economic development in coastal areas. Further, we use random forest regression and partial dependence plots to reveal the driving effect of the marine economy on the advancement of high-quality economic growth in China’s coastal areas. The results show that the driving effect of the marine economy on the high-quality development of coastal areas is affected by the moderating effect of the economic elements, and regions should choose their development paths according to the location of their elements in the optimal interval. Our research results can provide a scientific foundation for the formulation of differentiated economic high-quality development policies in China’s coastal areas.

Electrophysiological properties of dorsal root ganglion neurons cultured on 3D silicon micro-pillar substrates

BackgroundSilicon-based micro-pillar substrates (MPS), as three-dimensional cell culture platforms with vertically aligned micro-patterned scaffolding structures, are known to facilitate high-quality growth and morphology of dorsal root ganglion (DRG) sensory neurons, promote neurite outgrowth and enhance neurite alignment. However, the electrophysiological aspects of DRG neurons cultured on silicon MPSs have not been thoroughly investigated, which is of greatest importance to ensure that such substrates do not disrupt neuronal homeostasis and function before their widespread adoption in diverse biomedical applications. New methodWe conducted whole-cell patch-clamp recordings to explore the electrophysiological properties of DRG neurons cultured on MPS arrays, utilizing a custom-made upright patch-clamp setup. ResultsOur findings revealed that DRG neurons exhibited similar electrophysiological responses on patterned MPS samples when compared to the control planar glass surfaces. Notably, there were no significant differences observed in the action potential parameters or firing patterns of action potentials between neurons grown on either substrate. Comparison with existing methodsIn the current study we for the first time confirmed that successful electrophysiological recordings can be obtained from the cells grown on MPS. ConclusionOur results imply that, despite the potential alterations caused by the cumulative trauma of tissue harvest and cell dissociation, essential functional cell properties of DRG neurons appear to be relatively maintained on MPS surfaces. Therefore, vertically aligned silicon MPSs could be considered as a potentially effective three-dimensional system for supporting a controlled cellular environment in culture.

Study on the Impact of Carbon Emission Trading Pilot on Green Land Use Efficiency in Cities

Under the overarching principle of sustainability, the reliance solely on expanding the landmass to meet the demand for high-quality economic growth is unsustainable. To address the need for harmonious ecological–economic development, this paper examines the influence of carbon emissions trading (CET) policies on the urban land green utilization efficiency (LGUE) from an environmental regulation perspective. Harnessing municipal panel data from 278 cities across China between 2011 and 2020, the study initially employs a super-efficient SBM model to estimate the urban LGUE. Further, a progressive difference-in-differences methodology is utilized to delve into CET’s impact on the LGUE. The main results are as follows. (1) Through the visual analysis of the time–space evolution trend, the LGUE displays pronounced spatial agglomeration, with the LGUE values being higher in the central and western regions compared to the east, and in the south versus the north. Over time, it follows a “U-shaped” change pattern. (2) The CET policy exerts a statistically significant positive influence on the LGUE, although this effect is accompanied by a temporal lag. Following a number of approaches to validate the results, the impact remains significant. (3) Regarding the heterogenous effects, the CET policy appears to have a greater impact on resource-based cities and those in the eastern part of China relative to non-resource-based and central–western cities. This research offers empirical evidence and countermeasure recommendations for the further refinement of the CET policy to enhance the urban LGUE.

Green development represents a critical pathway to achieving high-quality growth. From a regional perspective, examining the impact of regional integration on urban green economic development holds significant importance. This study leverages a quasi-natural experiment of regional integration strategy implementation, utilizing unbalanced panel data from China’s ten major urban agglomerations and non-agglomeration cities from 2003 to 2022. Employing a multi-period difference-in-difference approach, we empirically assess the policy effects of regional integration strategies on urban green economic development. We further analyze the heterogeneity of policy effects in terms of the geographic areas, urban agglomeration scales, and development driving models of the cities under study. Lastly, we use a moderating effect model to explore the mechanisms through which regional integration strategies impact urban green economic development. The research results are helpful for promoting urban green economy development through a regional integration strategy.

Fabrication of low thermal resistance 3C-SiC/diamond structure for GaN epitaxial layer growth

Integrating diamonds with GaN presents a promising solution for enhancing heat dissipation. However, a critical challenge lies in developing an engineering substrate that facilitates the growth of high-quality GaN epitaxial layers, enabling the production of GaN-based devices with superior thermal management on a large scale. In this study, we have successfully developed an engineering substrate conducive to high-quality GaN growth. This accomplishment was achieved through the direct transfer of a 3 C-SiC thin film, originally grown on Si, to a diamond substrate at room temperature using the surface-activated bonding technique. After the transfer process, we observed the presence of a SiC amorphous layer at the interface, measuring approximately 18.5 nm in thickness. Notably, this thickness reduced to 14.5 nm after annealing at 1100 °C, indicating a transformation from amorphous to polycrystalline SiC due to recrystallization. Furthermore, it is crucial to highlight that no exfoliation of the 3 C-SiC/diamond bonding interfaces was observed even after subjecting them to annealing at 1100 °C. This observation is pivotal for ensuring the high-quality growth of GaN crystals on diamonds. The thermal boundary conductance of the 3 C-SiC/diamond interface reached nearly 93 MW/m2·K, demonstrating significant efficiency for device cooling. These compelling results highlight the potential of the 3 C-SiC/diamond engineering substrate to enable high-performance GaN-based devices, providing significantly enhanced thermal management capabilities. This breakthrough represents a major stride forward in the field.

Corporate carbon emissions management and the disclosure of key audit matters

The principle that sustainable development can foster high-quality corporate growth has gained popularity as a tool for environmental protection. Utilizing data of firms listed on Shanghai Stock Exchange and Shenzhen Stock Exchange from 2010 to 2020, this study investigates the impact of corporate carbon emissions management (CCEM) on the disclosure of key audit matters (KAMs). The findings indicate that CCEM can significantly elevate the adequacy of disclosure concerning KAMs. Tests on underlying mechanism underscore that accounting conservatism and audit quality serve as pivotal channels through which CCEM facilitates the disclosure of KAMs. Further analysis on economic consequences reveals that the disclosure of KAMs helps mitigate stock price crash risk while enhancing environmental, social, and governance performance. This study enriches research on factors influencing the disclosure of KAMs, concurrently providing valuable insights for advancing high-quality corporate development and facilitating communication between auditors and users of audit reports.

Impact of industrial policy on urban green innovation: empirical evidence of China’s national high-tech zones based on double machine learning

Effective industrial policies need to be implemented, particularly aligning with environmental protection goals to drive the high-quality growth of China’s economy in the new era. Setting up national high-tech zones falls under the purview of both regional and industrial policies. Using panel data from 163 prefecture-level cities in China from 2007 to 2019, this paper empirically analyzes the impact of national high-tech zones on the level of urban green innovation and its underlying mechanisms. It utilizes the national high-tech zones as a quasi-natural experiment and employs a double machine learning model. The study findings reveal that the policy for national high-tech zones greatly enhances urban green innovation. This conclusion remains consistent even after adjusting the measurement method, empirical samples, and controlling for other policy interferences. The findings from the heterogeneity analysis reveal that the impact of the national high-tech zone policy on green innovation exhibits significant regional heterogeneity, with a particularly significant effect in the central and western regions. Among cities, there is a notable push for green innovation levels in second-tier, third-tier, and fourth-tier cities. The moderating effect results indicate that, at the current stage of development, transportation infrastructure primarily exerts a negative moderating effect on how the national high-tech zone policy impacts the level of urban green innovation. This research provides robust empirical evidence for informing the optimization of the industrial policy of China and the establishment of a future ecological civilization system.

How enterprises' public welfare low-carbon behavior affects consumers’ green purchase behavior

The Chinese economy has undergone high-speed, high-quality growth, and the concept of low-carbon technology has gained popular support. Businesses and consumers must jointly endeavor to achieve low-carbon economic development. Moreover, it is important to investigate whether enterprises' low-carbon behavior is correlated with consumers' green consumption behavior. We built a theoretical model to depict the relationship between corporate public welfare low-carbon behavior, consumers' green purchase intention, and green purchase behavior. We then divided corporate public welfare low-carbon behavior into three dimensions. We proposed hypotheses, collected data through a questionnaire survey, and analyzed the data using statistical analysis software of SPSS 26.0 and AMOS 24.0. Public welfare low-carbon behavior was significantly correlated with consumers’ green purchase intention, and public welfare low-carbon participation and public welfare low-carbon motivation were significantly correlated with green purchase intention. Finally, we proposed suggestions from three perspectives: the public welfare low-carbon mechanism, public welfare low-carbon participation, and public welfare low-carbon motivation. The results provide theoretical support for research methods related to the low-carbon growth of enterprises and green consumption, as well as guidance and decision-making support for enterprises in carrying out cause marketing.

The swift progression of digital technology is leading to substantial shifts and evolutions within enterprises. In the evolving environment characterized by the integration of digital technologies and the physical market, it's essential to examine the effects of digitalization on the path of enterprises towards attaining superior growth quality. This study utilizes panel data from A-share listed companies in China's equipment manufacturing sector, spanning from 2013 to 2021, to perform an empirical analysis on the influence and mechanisms of digital transformation in fostering the progress of these companies towards high-quality growth. The results reveal that digital transformation plays a significant role in promoting high-quality development among equipment manufacturing enterprises, and these results remain consistent after implementing various tests to mitigate endogeneity and confirm the findings' reliability. The examination of mechanisms suggests that digital transformation significantly contributes to the advancement of equipment manufacturing companies by alleviating financial constraints, improving internal control quality, and facilitating the integration of environmentally friendly innovation technologies. Moreover, the impact of digital transformation on elevating the quality of development within equipment manufacturing companies is notably more pronounced in privately-owned firms, those located in the eastern region, and businesses classified as high-tech. This highlights how the nature of ownership, geographical location, and technological classification further amplify the benefits of digital transformation for high-quality growth in the sector. These findings offer a theoretical basis for assessing the economic implications of enterprises' digital transformation and for shaping relevant governmental policies.

Comparative Study on the Digital Economy Development Based on TOPSIS Comprehensive Evaluation: A Case Study of the Middle and Lower Reaches of the Yangtze River

Promoting the digital economy in the middle and lower reaches of the Yangtze River can not only boost the development of e-commerce, energy science and technology and other industries, but also pave the theoretical way for the digital economy development in various regions, so as to further provide an important practical basis for achieving high-quality economic growth. In this paper, seven provinces in the middle and lower reaches of the Yangtze River are taken as the research objects. Meanwhile, the development and different trends of the digital economy in each region are quantitatively analyzed and compared to propose suggestions for better development of the digital economy in the middle and lower reaches of the Yangtze River. On this basis, this paper first constructs the evaluation and measurement model of the digital economy development, and then gives the weights to the relevant indices through the analytic hierarchy process. After that, the regions in the middle and lower reaches of the Yangtze River are scored and compared via the TOPSIS comprehensive evaluation, which identifies that the mobile phone penetration, the number of Internet broadband access ports and the telecom business income are vital indices to accelerate the digital economy development. Finally, this paper argues that governments should increase investment in digital infrastructure construction and promote the deep integration of digital technology and industry.

The Spatiotemporal Impact of Digital Economy on High-Quality Agricultural Development: Evidence from China

China’s high-quality economic development is strongly supported by the high-quality development of agriculture, and the digital economy has emerged as a key driver for promoting shared prosperity and high-quality economic development. Against this backdrop, investigating the connection between high-quality agricultural development and the digital economy holds significant importance. This study utilized the entropy-weighted TOPSIS model to evaluate comprehensive evaluation indicators of the two according to panel data from 30 provinces in China between 2011 and 2021. Subsequently, GIS spatial analysis and exploratory spatial data analysis (ESDA) were employed to investigate the spatiotemporal evolution features and spatial correlations. Finally, the spatiotemporal geographically weighted regression (GTWR) model was constructed to examine the spatiotemporal impact of the digital economy on the advancement of high-quality agricultural growth. The results indicate that: (1) from 2011 to 2021, China’s high-quality agricultural development and digital economy both demonstrated a general increasing trend. In terms of spatial distribution, there were significant spatial variations, with a general trend of “Southeast is higher, whereas the Northwest is lower”. The regions with significant value were primarily clustered in the coastal areas in the east and several provincial capitals. (2) Both of the two exhibited significant global spatial self-correlation, and there were also significant spatiotemporal clustering effects in high-quality agricultural growth, gradually forming a high-value cluster centered around Shanghai and a low-value cluster centered around western provinces. (3) The digital economy positively influences the enhancement of high-quality agricultural development, demonstrating notable spatial and temporal heterogeneity. In contrast to the southeastern areas, the influence is more pronounced in the northern and central-western areas.

Reducing heat exposure from personal cooling strategies to green city construction in China's tropical city

With rapid industrialization and urbanization, the risk of summer heat exposure for urban dwellers has increased. The use of air conditioners (ACs) has become the most common personal cooling strategy, but further increasing fossil fuel consumption. As sustainable and affordable cooling strategies, urban parks can reduce heat exposure and substitute a part of air conditioners use. This study evaluates the heat exposure reduction from personal cooling to urban parks based on satellite images, questionnaire surveys, and network analysis in Liuzhou, one tropical city in China. We found that residents with lower income had a higher risk of heat exposure. Among the respondents, 85 % of residents chose to use ACs to alleviate high temperatures in summer, and 81.8 % among them were willing to access park cooling area (PCA) to cool off instead of using ACs. About one third parks could serve as potential alternatives (with temperatures <28 °C) to air conditioning, reducing carbon emissions by 175.93 tons per day during the hot summer and offsetting 2.5 % of urban fossil fuel carbon emissions. The design of parks should give more consideration to elder people and provide a good cooling platform for various social income groups. Future planning should also focus on accessibility to enable residents to fully utilize the parks. Building parks within 34.10 ha would provide a more efficient use of land. This research guides sustainable, high-quality growth in industrial cities and might contribute to promotion of low-carbon cities and social equity.

High-quality germanium growth on (111)-faceted V-groove silicon by molecular beam epitaxy

High-quality and low-defect-density germanium (Ge) buffer layers on silicon (Si) substrates have long been developed for group IV and III–V devices by suppressing defect propagation during epitaxial growth. This is a crucial step for the development of highly efficient photonic devices on Si substrates. Patterned silicon substrates have increasingly been employed for their ability to restrict and hinder the motion of defects. In this work, we demonstrate the effectiveness of an optimised two-step growth recipe structure on a (111)-faceted V-groove silicon substrate with a 350 nm flat ridge. This strategy successfully reduces the threading dislocation (TD) density while growing a 1 μm Ge buffer layer via molecular beam epitaxy. As a result, a high-quality buffer is produced with a low TD density on the order of 107 cm−2 and a surface roughness below 1 nm.

Investigation on the effect of chemical mechanical polishing sapphire substrate on chemical vapor deposition growth of two-dimensional MoS2

Two-dimensional molybdenum disulfide (2D MoS2), with atomic-level thickness, whose crystal crystallinity and size are easily influenced by the surface morphology of the substrate during growth. This work systematically investigates the impact of chemical mechanical polishing (CMP) sapphire substrate on chemical vapor deposition (CVD) growth of 2D MoS2. A green and highly efficient CMP method for the sapphire substrate is first proposed, whose maximum material removal rate (MRR) of 4.27 µm/h with surface roughness (Ra) of 0.10 nm (AFM, scanning area of 5 × 5 μm2) can be attained. The size and thickness statistics of 2D MoS2 domains grown on different substrates indicate that the CMP sapphire substrate in this work can promote the size and monolayer uniformity of 2D MoS2 during CVD growth. Meanwhile, Raman and photoluminescence (PL) spectra of monolayer MoS2 grown on different substrates also indicates the monolayer MoS2 grown on the CMP sapphire substrate in this work has superior crystalline quality and optical properties. The above findings have provided new insights into the mechanisms underlying 2D MoS2 growth on surfaces in various states and are expected to accelerate the development of large size large-size and high-quality growth of two-dimensional material for further device applications.

Analysis of the impact factors of industrial structure upgrading on green total factor productivity from the perspective of spatial spillover effects

Green development has already been a vital part of China's high-quality economic progress in the future, and accelerating the restructuring and improvement of the industrial structure plays a crucial roll in promoting a regional green economy. In this article, based on the data of 278 prefecture-level cities in China from 2011 to 2020, the SBM directional distance function and Malmquist-Luenberger (ML) index are used to gauge regional green total factor productivity (GTFP). The spatial Durbin model is also introduced to investigate the spatial spillover mechanism of GTFP and its influencing factors under the optimized and upgraded industrial structure. The study indicates that the optimization of the industrial structure have an important effect in promoting the growth of GTFP. Specifically, industrial structure integration has a greater bearing on the increase in GTFP, while there is a difference in the effectiveness of industrial structural advancement and rationalization of GTFP. Economic growth level inhibits the enhancement of GTFP, and urbanization level and industrial agglomeration have a significant negative impact on the enhancement of GTFP in the spatial dimension. On a different hand, foreign investment degree and government intervention level have a significant positive affect on regional GTFP. In addition, this study fills the research gap of the regional industrial structure upgrading influence on GTFP, which has great theory and practice value for promoting China's high quality growth of green economy.

At a time when China's economy is entering a new normal and realizing high-quality medium-speed growth, it is inextricably linked to the forty-two years of reform and opening up. As a pioneer of reform and opening up, Guangdong Province has been at the forefront of domestic economic development, demonstrating courage and practice in response to the changes of the times. As China's relationship with the world economy grows closer, changes in the international economy have prompted the deepening of regional economic integration and international trade. The application of free trade in international trade has been increasing, and FTAs have been widely practiced globally. As the world's second largest economic complex, China is still in the developing stage of free trade zone reform and practice compared with other developed countries. Wang Linghao (2019) pointed out that China's value and status in the global economy is increasing, and the development of free trade zones can help to enhance China's position in the global industrial chain. He emphasized that the influence of free trade can be enhanced through the development of free trade zones and the influence of the "Belt and Road" policy. Wang Under the guiding ideology of deepening reform and opening up of FTZs, China has promoted the experimentation and construction of Guangdong Qianhai FTZ and Hainan FTZ. Although the specific research on the business environment of Guangdong Qianhai FTZ has not yet formed a scale, it can be seen from the development research of other domestic FTZs that the business environment has an important impact on the construction of free trade zones. Therefore, this paper will deeply analyze the current situation and relevant initiatives of the business environment in Guangdong Qianhai FTZ from various aspects.
