Abstract

As an important part of the world economy today, the marine economy is of great significance for promoting economic growth and sustainable development. To better promote the development of marine economy, the Augmented Dickey-Fuller (ADF) unit root test was first used to test the stationarity of marine economy related variables to ensure the reliability of the model. Then, the Vector Error Correction Model (VECM) is used to analyze the long-term stable relationship and short-term dynamic adjustment relationship between the marine industrial structure rationalization and the marine economic growth. These results reveal the mechanism of the influence of the rationalization of marine industrial structure on the growth of marine economy. It is found that among the eastern coastal provinces and cities, the rationalization level of marine industrial structure in Shanghai is up to 0.163 points, which is higher than other cities. The main reasons are the low specialization index of marine labor force, the comprehensive utilization amount of industrial waste in 10,000 yuan of gross marine product, the low environmental protection index, and the large gap between the benefits of each index. In addition, the study also found that the Granger causality test values of the delayed combination of variables Gross Ocean Product (GOP), ts, GOP, and ts were 5.531, 14.672, and 15.069, respectively. Finally, it is found that the upgrading of marine industrial structure and the output of marine economy will correct the deviation of industry rationalization below the equilibrium value in the short term at a rate of 0.1675. According to the above results, the study puts forward the following suggestions. First, it needs to strengthen the planning and layout of the marine industry, rationally guide the allocation of resources and industrial development. Second, it needs to increase support for scientific and technological innovation, and promote technological progress and industrial upgrading. The third is to strengthen the government's policy support and supervision to provide a stable policy environment and market environment for industrial development. The innovation lies in the systematic study of the relationship between the rationalization of marine industrial structure and the growth of marine economy.

海洋产业结构合理化对海洋经济增长的影响
海洋经济作为当今世界经济的重要组成部分,对促进经济增长和可持续发展具有重要意义。为了更好地促进海洋经济的发展,首先采用增广Dickey-Fuller (ADF)单位根检验对海洋经济相关变量进行平稳性检验,以保证模型的可靠性。然后,利用向量误差修正模型(VECM)分析了海洋产业结构合理化与海洋经济增长之间的长期稳定关系和短期动态调整关系。这些结果揭示了海洋产业结构合理化对海洋经济增长的影响机制。研究发现,在东部沿海省市中,上海海洋产业结构合理化水平高达0.163点,高于其他城市。主要原因是海洋劳动力专业化指数低,万元海洋生产总值工业废弃物综合利用量大,环境保护指数低,各指标效益差距大。此外,研究还发现,延迟组合变量Gross Ocean Product (GOP)、ts、GOP和ts的格兰杰因果检验值分别为5.531、14.672和15.069。最后发现,海洋产业结构升级和海洋经济产出在短期内会以0.1675的速率修正产业合理化偏差低于均衡值。根据以上结果,本研究提出以下建议。一是加强海洋产业规划布局,合理引导资源配置和产业发展。二是加大对科技创新的支持力度,促进技术进步和产业升级。三是加强政府的政策支持和监管,为产业发展提供稳定的政策环境和市场环境。创新之处在于系统地研究了海洋产业结构合理化与海洋经济增长之间的关系。

期刊介绍: The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
