Hot spots, evolutionary trends, and future prospects for the sustainable development of the marine economy in the past 30 years: a comparative bibliometric analysis based on CiteSpace

How to assess the quality of sustainable development is an important issue for the marine economy. This study examined studies on sustainable development of marine economy over the past 30 years using core databases from China National Knowledge Infrastructure and Web of Science. This study introduced bibliometric analysis methods and CiteSpace software to track and comparatively analyze the hotspots of studies from 1994 to 2023. This study showed that (1) the research on sustainable development of the marine economy has achieved extensive results. Researchers have already collaborated with those in China. (2) Hotspots for Chinese research are mainly focused on building an indicator system of marine economy's sustainable development, realizing the path of sustainable development of regional marine economy, and planning the sustainable development goals of specific marine industries. In contrast, other countries focus on protecting marine ecology and identifying the path of sustainable development of the marine industry. (3) Strengthening exchange and cooperation between institutions and scholars from various countries, and further studies on the micro-paths of blue carbon sinks, marine ecological civilization and high-quality development, low-carbon development of marine industries will become new hotspots for research.

Construction of copper-functionalized two-dimensional zeolitic imidazole framework-7 (ZIF-7) nanosheets for enhanced antibacterial and antibiofilm performance

Marine biological pollution restricts the sustainable development of marine economy. Cu2O stands as a predominant antifouling agent for developing marine resources engineering. However, the problems of easy aggregation, rapid failure, and explosive release of copper ions limit the practical application of Cu2O. In this work, a novel copper-functionalized two-dimensional zeolitic imidazolate framework-7 nanocomposites ZIF-7@Cu2O was successfully fabricated by in-situ growth methodology. The emergence of ZIF-7@Cu2O nanocomposites solves the above problems in the use of Cu2O. Due to the huge specific surface area of the 2D ZIF-7 nanosheets and the electrostatic interactions, the cubic Cu2O, with a diameter of 250 nm, can be uniformly and firmly anchored on the surface of 2D ZIF-7 nanosheets, thus effectively avoiding the rapid dissolution of cuprous oxide and reducing the release rate of copper ions. Antibacterial experiments demonstrate that, in comparison to ZIF-7, Cu2O, and ZIF-7/Cu2O (physical mixture of ZIF-7 and Cu2O), ZIF-7@Cu2O exhibits superior antibacterial properties with 99.99 % against E. coli and the minimum inhibitory concentration (MIC) of 32 μg/mL. Furthermore, the reactive oxygen species (ROS) assay confirms ZIF-7@Cu2O could promote the generation of ROS. Antibiofilm formation results reveal that ZIF-7@Cu2O nanocomposites are effective in preventing biofilm formation of E. coli and P. aeruginosa at a low concentration (50 μg/mL). Finally, ZIF-7@Cu2O nanocomposites are employed as fillers to prepare ZIF-7@Cu2O/EP composite coating, the bactericidal kinetics and bacterial adherence on the coating surface are investigated. We believe this work could provide novel insights into the rational design of 2D ZIF-based material in the field of antifouling.

Ecodevelopment strategy selection and case simulation of marine ranching enterprises based on evolutionary games

In the context of China’s “dual carbon” goals of carbon peak and carbon neutrality, the ecodevelopment of marine ranching enterprises (MREs) can provide new opportunities for economic growth and environmental protection. MRE ecodevelopment not only enhances the value of enterprise products but also helps restore the marine environment and protect fishery resources, thus promoting the sustainable marine economy development. Since marine ranch development is guided by the government, government regulation and incentives play an important role in MRE ecodevelopment. Based on the principle of participating subjects’ limited rationality, this study constructs an ecodevelopment game payment matrix involving central government regulation, local governments, and MREs and analyzes their decision-making processes. Using MATLAB, parametric analysis and numerical simulation are conducted to reveal the development behaviors of the government and MREs and their influencing factors. The results are as follows: Initial willingness to participate has different influences on the two participating subjects. Government incentive policy has a greater influence on MREs, and the punishment by the central government and monitoring positively contribute to the behavioral choices of the MREs and the government. These findings can help governments formulate mechanisms to promote MRE ecodevelopment. Specifically, we recommended that the governments promote MRE ecodevelopment by establishing hierarchical supervision and management organizational systems, improving policy, and formulating reasonable reward and punishment mechanisms.

Evolution of marine ecology-industry symbiosis patterns and ecological security assessment: New evidence from coastal areas of China

Marine ecological security is an important precondition and foundation for the development of marine business. Scientific and effective assessment of marine ecological security is of great significance for promoting the sustainable development of marine economy and building an ecological civilization. Based on the symbiosis theory, this paper focuses on the key role of human economic activities in the evolution of ecological security from the perspective of eco-industrial symbiosis and constructs a symbiotic system of indicators considering human economic activities and all subsystems with the help of the “Driver-Pressur-State-Impact -Response (DPSIR) model” analysis logic. This paper adopts the Lotka-Volterra symbiosis model to dynamically analyze the causes of the symbiotic coupling relationship of marine ecological security in China's coastal areas from 2006 to 2019. The research results show that the socio-economic development index shows a stable upward trend, the environmental capacity index basically remains stable, and the ecological impact index shows a fluctuating and undulating trend. During the sample period, there were only four modes of mutualism symbiosis, ecological single damage, industrial single damage, and mutual harm symbiosis in coastal areas. Hebei, Guangdong, Guangxi, and Hainan provinces are dominated by the optimal ecological security state. Tianjin, Jiangsu, Shanghai, Zhejiang, and Fujian are mainly in the security transition area; Shandong and Liaoning provinces are in a state of ecological security dominated by non-safe areas. Finally, relevant policy suggestions are put forward, in order to provide decision-making reference for improving marine ecological security and promoting the healthy development of the marine industry.

Research on the Measurement and Countermeasures of Marine Green Economy Efficiency in China under the Background of “Double-Carbon”

Aims: It is of great significance to China to realize the green and sustainable development of Marine economy in the process of continuously and steadily promoting the practice of reaching carbon peak and carbon neutrality. In recent years, the measure of Marine green economy efficiency has attracted wide attention from academic circles.
 Methodology: Under the dual perspective of environmental constraints and government governance, this paper will, based on the panel data of 11 coastal provinces in China from 2004 to 2019, use the ultra-efficiency SBM model to measure the efficiency of Marine green economy in 11 coastal provinces in China, and conduct a static effect analysis. At the same time, the traditional DEA model is adopted to calculate the Marine economic efficiency without considering the unexpected output and resource input, and the two calculation results are compared and analyzed.
 Conclusion: (1) the overall efficiency level of Marine green economy in China is not high; (2) the undesired output has obvious influence on the efficiency value of Marine green economy, and the resource and environmental constraints will cause a certain degree of resource loss; (3) due to the economic development level and regional differences in different provinces, some provinces improve the Marine economic efficiency by sacrificing the environment. Finally, based on the above conclusions, targeted suggestions are put forward for the development of China's Marine economy to develop the Marine economy and accelerate the construction of a maritime power.

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.

A network analysis of carbon emission flows among marine industries in China

In recent years, environmental problems have become an important bottleneck restricting the sustainable development of Marine economy in China. CO2 is one of the main greenhouse gases which contributes to marine environmental problems. As CO2 emissions can transfer among industries, identifying the industries that release CO2 most and clarifying the carbon emission flows among marine industries are helpful for decision-makers to curb CO2 emissions of marine industries. This paper applies the network method to measure carbon emission flows. First, carbon transfer coefficient is calculated. Second, carbon transfer network of marine industry is constructed based on carbon transfer coefficient. Then the structure of marine industry carbon transfer network is analyzed. Finally, the method proposed in this paper is applied to the case of China and some suggestions for carbon reduction is put forward.

Assessment of Conductivity-Temperature-Depth via multi-criteria approach: Regret theory based model on the pythagorean fuzzy environment

Sustainable development of marine economy requires strengthening the marine environmental monitoring and management. Conductivity-Temperature-Depth (CTD) realises multi-dimensional monitoring of marine environment by measuring the traits of seawater. To further promote real-time online marine monitoring, conducting a robust assessment of CTD equipment is a primary task for capacity building. In this paper, to evaluate several equipment options, a multiple-criteria decision-making model, based on regret theory and squared-confidence Pythagorean fuzzy hybrid weighted arithmetic and geometric aggregation (SCPFHWAGA) operator is proposed. The SCPFHWAGA operator takes into account the confidence level, which enhances the comprehensiveness of information aggregation. In addition, considering the differences in subjective confidence in equipment use, social network analysis and regret theory are introduced. The evaluation criteria are then designed with the concerns raised before, during and after using the equipment, which reflects the whole process of CTD equipment evaluation more objectively. The case of Zhejiang (China) is analysed. The robustness and validity of the proposed framework are verified by comparing the results with those obtained using other methods.

Preliminary Study on Marine Ecological Environment Problems and Prevention Points in Fujian Province

With the gradual promotion and implementation of the strategy of Fujian Province as a strong marine economy, the marine economy of Fujian Province has been effectively developed. However, due to various historical reasons, long-term indiscriminate exploitation of marine resources, dredging, damming and predatory development of marine tourism have led to the destruction of marine ecosystems and seriously restricted the sustainable development of marine economy. Based on the reading and research of numerous relevant literature, this paper integrates and expounds the current situation and background of marine pollution investigation in Fujian Province, analyzes and puts forward the corresponding prevention and control measures and key points.

Vulnerability assessment and impact factor analysis of marine economic system based on fuzzy comprehensive evaluation model

It is crucial to examine the vulnerability of the marine economy and analyze the main influencing factors to promote the sustainable development of marine economy. In this rearch, a vulnerability assessment index system of marine economic system was constructed from four aspects: stress, sensitivity, elasticity and response ability. Combined with the coefficient of variation method, 40 assessment indexes in the index system were objectively selected and reduced. Based on the assessment set obtained from the fuzzy comprehensive evaluation model, the weighted average method and weighted linear sum method were used to measure the vulnerability level type and evolution characteristics of the marine economic system. The key influencing factors were analyzed using a principal component analysis. We found that the vulnerability of Jiangsu's marine economic system in 2007–2016 was moderate and low, and it was significantly improved during 2012–2015, especially in 2015, it was mild vulnerable and below. The GDP of coastal areas, fixed asset investment of the whole society, value added of marine and related industries, coastal wind power generation capacity, per capita consumption expenditure of urban residents and list all were the key factors affecting the vulnerability of the marine economy. We analyzed the characteristics and influencing factors of vulnerability change and put forward targeted suggestions.

The internal dynamics and regional differences of China's marine economic evolution based on comprehensive evaluation

The marine economy has always occupied an important position in China’s economic development. It is not only an important element of the national economy but also the primary economic form in coastal areas. In recent years, China’s economy has been growing at a rapid pace, and the marine economy’s share of GDP has expanded as well. However, it is undeniable that the sustainable development of marine economy is also confronted with unprecedented challenges, such as sea pollution and the degradation of coastal ecosystem, etc. This article aims to prevent the predatory growth of the marine economy, to promote sustainable development, and to achieve the coordination and unity between marine economy and marine ecology, culture, resources and technology. This study explores the internal motivation of the sustainable evolution of marine economy and develops a new indicator system using data from 11 coastal areas in China from 2008 to 2018. The level of sustainability of the marine economy in China's coastal areas is evaluated using a combination of entropy and the improved topsis method. Results show that technological innovation driving has gradually replaced the resource-invested growth model. From 2008 to 2018, the sustainability of marine economic development in China's coastal areas showed a stratified trend, with obvious differences between different regions. Among them, the sustainability of Guangzhou was as high as 0.445, the development efficiency of Tianjin and Shanghai was higher, and the total marine economy of Zhejiang and Jiangsu was high but the sustainability was weak. Finally, we discussed the causes that contribute to regional disparities and offered recommendations.

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.

How do environmental regulation and technological innovation affect the sustainable development of marine economy: New evidence from China’s coastal provinces and cities

As marine economy has entered a new normal, the transformation and upgrading of marine economy has reached a crossroads in coastal regions, and there is an urgent need to change the development mode and the growth momentum of marine economy. Exploring reasonable environmental regulation means and appropriate environmental regulation intensity to promote green technological innovation and lead the transformation of marine economy is the only way for China's marine sustainable development in the future. Through theoretical analysis and empirical tests, this study examines the influential mechanisms of environmental regulation and technological innovation on GTFP of marine economy to provide a theoretical basis for local government and enterprises to make decisions under environmental regulation. The empirical process adopts a direct effect, an intermediary effect, and a threshold effect model based on panel data from 11 provinces and cities in China's coastal regions. The results show that China's marine environmental regulation is still in its initial stage, which is not conducive to the improvement of GTFP of marine economy. Technological innovation plays an intermediary role between environmental regulation and GTFP of marine economy, but the intermediary effect is very small-only 0.0920, so there is still significant room to improve. During the sample period, taking marine technological innovation as the threshold variable, environmental regulation has significant double threshold effect of technological innovation on GTFP of marine economy. Different levels of technological innovation decide which effect, either the “offset effect” or the “compensation effect” dominates. Finally, this paper puts forward the corresponding policy recommendations.

Grey correlation analysis on the synergistic development between innovation-driven strategy and marine industrial agglomeration: based on China's coastal provinces

PurposeThe implementation of the innovation-driven development strategy is of practical significance for improving the quality and efficiency of economic growth and accelerating the transformation of economic development mode. The purpose of this paper is to study the impact of innovation-driven strategies on marine industry agglomeration and industrial transformation.Design/methodology/approachIn traditional grey correlation analysis, when the positive and negative areas cancel each other out during the integration process, the calculation result of the correlation degree is often inconsistent with the qualitative analysis. For this reason, from the perspective of curve similarity, this paper constructs two response curves through the relative change area of the two curves and the relative area change ratio of similar degree, thus constructing an improved grey relational model.FindingsThe authors find that the innovation investment has a better correlation with marine industrial agglomeration. It also found that Guangdong Province has the highest degree of correlation between innovation indicators and marine industrial agglomeration. Much beyond the authors’ expectation, in the areas where marine industrial agglomeration is high, the synergistic effect is not obvious by using the location entropy method.Originality/valueThe improved grey correlation analysis method can effectively overcome the phenomenon that the positive and negative areas cancel each other in the integration process of the original algorithm, and it can also effectively measure the negative correlation between variables. This paper explores the impact of innovation drive on the agglomeration of marine industries, which is of great significance to the sustainable development of marine economy.

Spatiotemporal changes caused by the intensive use of sea areas in the liaoning coastal economic zone of China.

Oceans and their resources are experiencing immense pressure because of human exploitation. The intensive use of sea areas has become an important method in solving the contradiction between ocean supply and demand, thereby ensuring sustainable marine economy development, tapping potential sea-area utilization, reasonably allocating sea-area utilization structures, and increasing marine economic benefits. This paper explores the definition and connotation of intensive sea-area use and constructs an evaluation index system based on marine input intensity, marine utilization structure, marine economic benefit, and marine ecological environment. Multi-objective variable fuzzy set theory and fuzzy decision analysis methods were used to evaluate the intensive sea-area utilization in the Liaoning Coastal Economic Zone of China during 2004–2016. The spatial differentiation characteristics of intensive sea-area use were analysed using cluster analysis. The research result showed that: (1) Intensive utilization level of the Liaoning coastal economic zone has gradually increased, while it is still in a moderately weak level; (2) Sea area intensive utilization varied in degrees and fluctuates in the six cities under the jurisdiction of the Liaoning coastal economic zone; and (3) Marine input intensity, marine utilization structure, marine economic benefit, and marine sustainability indexes have increased in the cities, thereby exhibiting improvements in the Liaoning coastal economic zone.
