Impact of the coupling relationship between marine industry and regional development on the marine economy

To investigate the relationship between the marine industry and regional development, and assess its impact on the marine economy. The study creates an evaluation index system for the coupling relationship between the marine economy and regional development. It applies coupling theory and combines the hierarchical analysis method with the entropy weight method to determine the weight of each index. By constructing the coupling degree and coupling coordination degree model, this paper quantitatively analyzes the coupling relationship and applies the coefficient of variation to assess the coordinated development differences between different regions. The study utilized data from the official China Marine Statistical Yearbook. The analysis revealed an upward trend in the coupling degree of the marine economy and regional development during the study period, increasing from 0.58 to 0.72. This indicated a significant strengthening of the interaction and synergistic development between the two. In typical coastal areas, the coupling degree increased from 0.62 to 0.78, indicating the significant contribution of the marine industry to the region's comprehensive economic development. The study proposes policy recommendations to enhance the adjustment of the marine industrial structure and technological innovation, promote inter-regional cooperation and resource sharing, and strengthen marine environmental protection and sustainable resource utilization. These measures aim to promote the development of the marine economy while safeguarding marine resources.

New developments and trends in extended continental shelf delineation practices—An analysis of China's participation and response strategies

Rights and interests concerning the continental shelf beyond 200 nautical miles (extended continental shelf, ECS) are related to important aspects of a nation's marine utilization such as marine resource development, marine technological innovation, and the construction of marine ecological civilization. China is a country with a long coastline and has the right to delineate large areas of ECS according to the United Nations Convention on the Law of the Sea (UNCLOS). However, the process of confirming China's ECS rights under international law is particularly complicated owing to the complex maritime delineation disputes between China and its neighboring countries. From the perspective of international law, this study uses the method of historical analysis and case analysis to retrospectively explore the evolution of the international legal frameworks governing ECS and analyze its current characteristics and trends in practice. On this basis, the paper evaluates the major challenges of China's national practice in ECS delineation and puts forward suggested countermeasures for safeguarding its legitimate rights and interests related to ECS.

The coordination of technological and financial innovation concepts on the marine economy and its ecological development

This study first constructs an evaluation index system based on the pressure state response model, and assigns weights through entropy method and coefficient of variation method, providing theoretical and methodological support for comprehensive measurement and evaluation. Second, the least squares decision model is introduced and the PVAR model is used to analyze the development level of China's marine economy, ecology, and technological and financial innovation. The results indicated that from 2012 to 2022, the marine economic development level, marine ecological development level, and marine technology and financial innovation development level of 9 coastal provinces in China all showed a certain growth trend. However, in terms of the level of marine ecological development, various provinces had shown a downward trend, with Hebei performing the best, with an average of 0.230. Although various regions have achieved significant development in marine economy, ecology, and technological and financial innovation, the level of development varies among regions, and some regions have relatively low levels of technological innovation. The pressure and challenges between the marine economy and ecological environment protection caused by these real environments remain significant.

The ecological environment (EE) is an important factor affecting the sustainable development of the marine economy (ME): achieving coordinated development between the ME and EE remains a problem to be explored. From three perspectives—comprehensive development level, coupling coordination degree spatiotemporal analysis, and obstacle degree recognition—this paper explores the development level and spatiotemporal evolution characteristics of ME and EE coupling coordination in 11 coastal areas in China from 1999 to 2019. The results indicate the following: (1) During the research period, the comprehensive development levels of the ME and EE in China’s coastal areas continued to improve, with relatively high levels of economic structure subsystems and pressure subsystems. (2) There was a clear coupling relationship between the ME and EE, with a high degree of coupling, mainly consisting of high-quality coupling and good coupling. The increase in coupling coordination was significant, especially in Guangdong, Shandong, and Liaoning. (3) The analysis of the obstacle degree found that the crucial obstacle elements affecting the coordinated development of the ME and EE included the ME vitality subsystem and the EE response subsystem. Finally, policy suggestions are put forward, including promoting the development of an ecotype ME, promoting marine technology innovation, and adopting differentiated EE governance policies according to local conditions. This study helps evaluate the development capacity of the ME in China’s coastal areas and provides a basis for formulating targeted ME development strategies.

The development model of marine science and technology innovation under the background of regional integration in the Yangtze River Delta in the new era

Abstract In the wave of regional integration of the Yangtze River Delta, there are many geographical and institutional problems and asymmetries in knowledge and cultural systems in the regions, resulting in less efficient development, which creates many uncontrollable factors for integration and hinders it. Based on the entropy value method - three stage DEA model, firstly, We first measured the comprehensive evaluation index of each region’s development using the entropy method and assessed the marine economy of 11 regions in the Yangtze River Delta, we excluded some factors and random disturbances to calculate the innovation efficiency of marine science and technology (hereinafter referred to as IEMST) in China’s Yangtze River Delta region from 2010 to 2020. The results indicate that the overall level of IEMST is low in the 11 regions and is strongly influenced by regional differences. IEMST scale efficiency is too low to limit the improvement of China’s IEMST, we have to improve IEMST, through unified planning, adjustment, configuration of regional some factors, the establishment of a new model of IEMST development, further development of China’s marine science and technology, for China to form an innovation-driven development of science and technology to promote the great power of the sea has a positive impact, to promote the implementation of the marine power strategy.

Measuring the Sustainable Development of Marine Economy Based on the Entropy Value Method: A Case Study in the Yangtze River Delta, China

The rapid growth of the marine economy has provided a strong impetus for the economic development of the Yangtze River Delta region, but it has also posed serious challenges to the ecological environment of the marine watersheds in which it is located. To investigate how to promote the sustainable development of the marine economy in the Yangtze River Delta region, this study used relevant statistical data from 2009 to 2019, combined with four factors—marine economy, marine resources, ecological environment, and scientific and technological innovation—to build an evaluation index system for the sustainable development of the marine economy and employed the entropy value method to conduct a deeper investigation. It was found that there are problems in the sustainable development of the Yangtze River Delta marine economy, such as imperfect marine industry structure, significant differences in resource allocation, insufficient support capacity of marine science and technology innovation, and insufficient ecological environmental protection. Therefore, the study suggests promoting regional collaboration in the Yangtze River Delta, improving technological innovation, and enhancing environmental protection to support the sustainable development of the regional marine economy.

The impacts of extreme marine weather and marine scientific and technological innovation on marine economic development: Evidence form China’s coastal regions

The extreme marine weather is a very vital factor and has important implications for of marine economic development. However, there is a lack of systematic and quantitative analyses of its impact on the marine economic development. Here, we study the impacts of extreme marine weather on marine economic development of 11 coastal regions in China, using the dynamic panel model. We found that extreme marine weather exerts a significant negative impact on the marine economic development. The marine scientific and technological innovation promotes marine economic development in a prominent manner. The marine scientific and technological innovation slows down the unfavorable impact of extreme marine weather on the marine economy. After considering different industries for marine economic development and heterogeneity, we found that extreme marine weather and marine scientific and technological innovation have a great impact on marine economic development in the tertiary industry and the areas with high development concerning marine economy level, while deliver a small impact on the marine economic development in the primary industry and the areas low development level. This paper empirically studies the relationship between the two variables of marine extreme weather and marine science and technology innovation and its impact on marine economic development, enriches the research perspective of extreme weather on marine economic development, and provides new method evidence for improving the level of marine scientific and technological innovation and promoting the development of marine economy.

Resource Constraints and Economic Growth: Empirical Analysis Based on Marine Field

To explore the contribution of marine resources to marine economic growth, this study uses panel data from 2006–2019 across 11 coastal provinces and cities in China and establishes threshold regression models using marine capital, labor, and science and technology as threshold variables affecting marine resources and economic growth. The findings reveal that the impact of marine resources on marine economic growth only demonstrates a single threshold effect under the primary industry marine resources; in general, with increased capital investment, the marine economy presents a positive development trend. The impact of primary and secondary marine resources on marine economic growth has a single threshold effect of labor input, while the impact of tertiary marine resources on marine economic growth has a double threshold effect of labor input. With investment in marine science and technology, marine resource development and utilization in the primary industries have played a consistent role in promoting marine economic growth. However, the impact of this role is gradually decreasing; marine resource development and utilization in the secondary and tertiary industries shows a development pattern wherein the driving effect of marine economic growth is first large, then small, and then large again. Based on the above analysis, China should promote the transformation of labor-intensive to capital-intensive industries by increasing investment in marine capital, training marine talent, and developing marine science and technology innovation to increase the development level of China’s marine economy.

Empirical study on green development of marine economy driven by marine scientific and technological innovation and its influencing factors

In this study, the green development of marine economy driven by marine scientific and technological innovation is empirically studied and the influencing factors are analyzed. The results show that the development of marine science and technology is significantly positively correlated with the green development of marine economy as a whole, and each input variable has a promoting effect on economic development, but with varied degree of effect. The analysis on the growth models of “Circum-Bohai Sea Economic Zone,” “Yangtze River Delta Economic Zone” and “Pearl River Delta Economic Zone” shows that at present, science and technology in each marine economic zone play an obvious role in promoting economic development, and each input variable plays a different role in promoting the green development of regional marine economy. With the help of threshold panel model, the influences of five factors, namely opening to the outside world, government investment, financial development, human capital and technology investment, on the green development of marine economy driven by marine scientific and technological innovation are investigated, and it is concluded that all kinds of external influencing factors will interfere with the role of marine scientific and technological innovation and achieve the effect of promoting or restricting it.

Has Digital Finance Made Marine Energy Carbon Emission More Efficient in Coastal Areas of China?

Energy is an essential material foundation for ensuring economic sustainability and national security. With the development of digitalization, the importance of digital finance in promoting the green and low-carbon transformation of the economy has emerged. The ocean is a national energy treasure house. In order to explore whether digital finance improves the carbon emission efficiency of marine energy, this paper selects panel data from 11 coastal areas from 2011 to 2019 in China and uses the panel fixed effect model, mediation, and moderation model to analyze the mechanism between them empirically. The results show that: (1) digital finance improves marine energy carbon emission efficiency, and the depth of use has the most obvious effect; (2) the incentive effect is heterogeneous due to different geographical locations, resource endowment degree, and digitalization degree; (3) the marine energy consumption structure plays a mediating effect, and marine industrial structure and technological innovation can enhance the impact of the digital finance on marine energy carbon emission efficiency. Therefore, optimizing the energy consumption structure and giving full play to the effect of digital finance in promoting the efficiency of marine energy carbon emission to help accelerate the low-carbon development of China’s economy and the realization of carbon emission reduction.

How do heterogeneous environmental regulations affect the sustainable development of marine green economy? Empirical evidence from China's coastal areas

Under the dual constraints of environment and resources, it is imperative for China to achieve sustainable development of its marine economy through establishing effective mechanisms and intensifying environmental regulations to promote green transformation of the marine economy. By incorporating both marine economic development factors and environmental pollution factors into the marine green economy development evaluation system, this study measures the marine green economic efficiency (MGEE) in China. On this basis, the dynamic panel smoothed transition regression model is used to analyze the nonlinear effect and transition mechanisms between environmental regulation and marine green economic efficiency, and the heterogeneous effects of market-based and command-and-control environmental regulation tools are examined by distinguishing the forms of environmental regulation as well as regional development differences. The findings are as follows: ①under the setting of different transition variables, both market-based environmental regulation (MER) and command-and-control environmental regulation (CER) exhibit a non-linear relationship with MGEE during the transition between the high regime and the low regime. ②Both CER and MER contribute positively to the advancement of MGEE after exceeding certain thresholds through changes in the marine industry structure (MIS) and marine technology innovation (MTI). The driving impact of CER is noticeably stronger than that of MER after the threshold of MIS is exceeded, whereas the driving effect of MER is stronger after the threshold of MTI is exceeded. ③When foreign direct investment (FDI) is considered as the transition variable, CER consistently inhibits the growth of MGEE, however, MER's impact progressively changes from negative to positive with FDI surpassing the threshold.

Performance Analysis of Marine Ecological Environment Governance Based on DPSIR and Entropy Weight TOPSIS Model

In order to solve the global marine ecological environment problems and ensure their own marine strategic interests, we should participate in the global marine ecological environment governance in an all-round way. There are still some problems in the evaluation system, supervision mechanism, and performance evaluation of the marine ecological environment. Considering the impact and analysis on the ecological environment in the effect of marine governance, this paper puts forward the performance analysis of marine ecological environment governance based on DPSIR (Drive Pressure State Impact Response) and entropy weight TOPSIS model and constructs the performance index evaluation system of marine ecological environment governance combined with the current situation of marine ecological environment governance. Using entropy TOPSIS (technique for order performance by similarity to ideal solution) model and geographic detector, this paper explores the influencing factors of governance performance. From the perspective of marine ecological environment governance effect, the governance effect is good. The influence of pressure factors such as ecological environment, population, and economy is generally large. The main causes of marine environmental pressure are the massive amount of industrial wastewater, the utilization of water resources in coastal areas, and the employees involved in the sea. Through the factor detection method of geographic detector, the strength calculation of the three criteria of pressure-state-response which affect the performance level of marine environmental governance is carried out, and the pressure layer index, state layer index, and response layer index have good response. In marine science and technology innovation ability, government investment in marine construction has a significant impact on environmental governance performance.

Coupling Coordination between Marine S&T Innovation and the High-Quality Development of the Marine Economy: A Case Study of China’s Coastal Provinces

Promoting coupling coordination between marine scientific and technological (S&T) innovation and the high-quality development of the marine economy is an important measure to realizing sustainable marine development. Based on the complex adaptive systems theory, sustainable development theory and regional coordinated development theory, this study analyzed the coupling coordination and its influencing factors between marine S&T innovation and the high-quality development of the marine economy with China’s coastal provinces as study areas. The result showed that: (1) The coupling coordination fluctuated upward, changing from on the verge of dissonance to well-coordinated. (2) There was an agglomeration of high-level coupling coordination in central and eastern coastal provinces while the polarization between high-level and low-level coupling coordination was significant. (3) The improvement of coupling coordination mainly depended on the consumption expansion demand, multidimensional spatial integrated development, and industrial improvement demand. Regional heterogeneity of influencing factors existed in southern and northern coastal regions. (4) To improve coupling coordination, we should establish a demand-oriented mechanism for coordinated development between marine S&T innovation and the marine economy, and strengthen the multi-dimensional spatial planning and the guidance and guarantee functions of coastal governments, in particular to introduce and implement policies that suit local conditions. This research may supplement and improve the theoretical discussion and practical experience concerning sustainable marine development.

Impact of sci-tech finance on the innovation efficiency of China's marine industry

To realize the high-quality development of China's marine economy, it is important to vigorously promote blue finance and increase the support of science and technology finance for the innovation development of the marine industry. Based on the existing literature research, this paper uses two-step empirical evidence to investigate the role of science and technology finance on the innovation efficiency of the marine industry by combining the development status of science and technology innovation, science and technology finance in the marine industry. The results of the study show that government financial investment in science and technology finance has a significant contribution to the innovation efficiency of the marine industry; The innovation efficiency of marine industry is positively but not significantly affected by the investment of enterprises' funds in science and technology, and the innovation efficiency is inhibited by the investment in entrepreneurial risk management. In addition, there are still large differences in the efficiency of innovation in the marine industry among different regions. Moreover, we propose the government support the marine industry science and technology innovation fully, optimize risk investment and improve the investment return guarantee mechanism, and unblocked the indirect financing channels of the financial market for the sea-related science and technology innovation enterprises, and give policy recommendations to develop the marine industry science and technology innovation activities.

Exploring the relationship among marine science and technology innovation, marine finance, and marine higher education using a coupling analysis: A case study of China's coastal areas

The issue of marine sustainable development has become a bottleneck that restricts the high-quality development of marine economy. Marine science and technology (S&T) innovation, marine finance, and marine higher education interact and influence each other, and the three have a role in promoting the sustainable development of marine economy. This research analyzed the interaction among marine S&T innovation, marine finance, and marine higher education from the perspective of system coupling and constructed a marine S&T innovation-finance-higher education composite system. Moreover, this research took 11 coastal provinces and cities in China as the research objects, constructed the evaluation index system of marine S&T innovation-finance-higher education composite system, and used the coupling coordination model to study the spatial and temporal characteristics of the coupling coordination level of the marine composite system from 2006 to 2016. Furthermore, this research predicted the coupling coordination level of the marine composite system from 2017 to 2026. The results showed that the degree of interaction among the three subsystems in the marine composite system was strong. The coupling and coordination level of the marine composite system was improved in general, but there were significant differences among provinces and cities. The coordination level of the marine composite system showed an apparent spatial correlation, and the correlation showed an evident trend of enhancement. This study will help relevant departments formulate more effective policies for marine S&T innovation, marine finance, and marine higher education and provide references for decision-making to promote the coordinated development of the three and achieve sustainable development of marine economy.

The results show that (1) there are large gaps in the level of marine industrial structure rationalization across coastal areas, though the relative gaps in industrial structure advancement are small; and (2) marine science and technology innovation plays a significant role in promoting rationalization and advancement of the marine industrial structure. Finally, according to the research results, we put forward suggestions to promote the optimization and upgrading of marine industrial structure: we should strengthen the ability of marine science and technology innovation, attach importance to the cultivation of marine science and technology talents, improve the financial support for marine science and technology innovation, deepen international cooperation and maintain the “steady growth” of foreign investment.

Can economic development alleviate storm surge disaster losses in coastal areas of China?

Storm surge disasters are a major obstacle to the sustainable and healthy development of China's marine economy and society. By constructing a comprehensive index of storm surge disaster losses, this study uses the feasible generalized least squares (FGLS) method and impulse response analysis to evaluate the impact of the economic development level of 11 coastal areas on storm surge disaster losses from 2007 to 2016. The results show that a higher level of economic development in coastal areas increases the magnitude and duration of losses owing to storm surge disasters. With green marine science and technology innovation, the upward pressure that economic development exerts on storm surge disaster losses can be weakened, or even eliminated. Therefore, the economic development in coastal areas should be accompanied by enhanced green marine science and technology innovation. It is also necessary to accelerate the cultivation of sea-related skills, strengthen the environmental regulation, and improve early warning technology to reduce the losses caused by storm surge disasters.
