Comparative Study On The Development Of Marine Economy Around Bohai Region

China is a long-established oceanic country with abundant marine resources and marine development experience.Due to the traditional "heavy land and sea" ideology and various warfare factors,China's marine industry has not been truly rejuvenated.Until the 1990 s,the boom in marine development in the coastal areas began to spread,and the marine economy continued to develop rapidly.Since the party's 18 th National Congress proposed a major strategy for building a maritime power,the country has successively introduced a series of policy concepts for the development of the marine economy.During the “Twelfth Five-Year Plan” period in China,the marine economy is developing space for development,building marine ecological civilization,accelerating power conversion,and playing a vital role in maintaining sustained and stable economic growth.The “13th Five-Year Plan” period is a crucial period for China's in-depth adjustment of the marine economic structure and the acceleration of the transformation of the economic growth model.It insists on the coordinated development of the coastal and inland areas and firmly grasps the major opportunities for the“One Belt and One Road” initiative to promote the health of the marine economy.development of.The fifth meeting of the 18 th CPC National Congress once again emphasized the five major development concepts of firmly establishing and accurately implementing innovation,coordination,green,openness,and sharing.The marine economy,as an important part of the national economy,implements the innovation,coordination,and coordination of the marine economy.Green,openness and sharing are particularly important.Nowadays,the Chinese economy has developed into an export-oriented economy that is highly dependent on the oceans.In 2017,the total value of China's marine economic production reached 7761.1billion yuan,an increase of 6.9% over the previous year,and the total marine production value accounted for 9.4% of the GDP.The development of the marine economy is excellent.With the implementation of the “Machinery of the Sea” and the “Maritime Silk Road”strategy,the marine economy has gradually become the blue engine of China's economic growth,and the structure of the marine industry has been continuously optimized.The proportion of the three industries was changed from 5.7:47.3:47.0 in 2006 to 2017.Years4.6:38.8:56.6,the "three,two,one" type structure has basically taken shape.Regional economic differences have always been a research hotspot in economic issues.The marine economy belongs to the category of regional economic research.Nowadays,China has formed three major marine economic patterns in the north,east and south of the coastal areas.With the continuous improvement and optimization of the “three-circle” pattern,various marine economic circles are making efforts to give full play to regional advantages and fully promote the development of China's marine industry..In 2016,the total value of marine production in the Bohai Rim region accounted for 34.5% of the country's total marine production value.It can thus be seen that the Bohai Rim region is an important part of China's marine economy and plays an important role in the development of China's marine economy.In this paper,the quantitative analysis method is used to calculate and analyze the economic development situation in China's Bohai Rim region.First of all,using the variation coefficient,standard deviation and Theil index to study the differences in the level of marine economic development in the Bohai Rim region,the main conclusions obtained are that the absolute difference in economic development in the Bohai Rim region has gradually expanded,but it has obvious stages..Second,using the three-axis graph method and the deviation-share analysis method to analyze the tertiary ocean industry structure in the Bohai Rim region,we conclude that the industries in the Bohai Rim region are more reasonable.Between 1996 and 2005,Tianjin and Shandong experienced rapid growth and competition.The force is higher than Liaoning and Hebei,and the results did not change significantly between 2006 and 2015.However,the combined effects of marine industrial structure and industrial competitiveness have a strong leading role in the development of marine industries in Tianjin and Shandong,and the role of Liaoning and Hebei.It's not big.From the perspective of the effects of the internal evolution of the industrial structure on the marine economy,the leading factors in the development of marine economy in the Bohai Rim region are the secondary and tertiary industries in the ocean.Finally,according to the Gini coefficient decomposition decomposition result,it can be concluded that the concentration effect can weaken the Gini coefficient,indicating that the control of provincial economic disparities depends on the concentrated development of the industry,and the structural effect can expand the provincial economic disparities,but the expansion rate tends to be flat and its impact is not.Big.
