Study On The Relationship Between The Service Industry Structure Optimization And Economic Growth In Tianjin

In the modern economic society, the service industry has become a powerful engine to promote economic growth. Tianjin as the center city of the Bohai Economic Rim, the development of its service industry not only affects their level of modernization and competitiveness, but also affects the economic development of the entire economic region. Although Tianjin service industry has made some breakthroughs, but compared with developed cities, the structural optimization and output growth, etc., there are still some gaps. Under the background of economic globalization, the service sector is lagging behind may become a bottleneck restricting the future development of Tianjin in the future. Therefore, the research of Tianjin service industry is the relationship between the sustainability of rapid development and the urban competitiveness of major issue. It is necessary to carry out system analysis of the internal structure of service industry in Tianjin, to explore factors restricting the development of structures and seek the path of structural optimization.In this paper, it studies the relationship between Tianjin internal service structure and economic growth. According to its development present situation, influence factors, structure and competitiveness effect analysis of the actual situation to optimize adjustment, in order to achieve rapid economic growth in Tianjin. First of all, according to the related literature at home and abroad combing the related service industry internal structure and economic growth theory system include industrial structure change theory, services mechanism of internal structural changes, economic growth theory. Second, according to the theories of the service industry and its internal structure, the related economic growth and the historical data of service industry development in Tianjin, Tianjin three times industry development present situation and the contribution of three times industry on economic growth of Tianjin is studied of the industrial structure. And compared with the national, Beijing, Shanghai, it makes a detailed analysis of the internal structure of service industry in Tianjin, and proposes a few of problem about the internal structure of the service sector include the small total size, slow development of new services, low openness, low market level and so on. Again, it analyzes the factors influencing the internal structure of service industry in Tianjin, and builds nine factors indicators. It analysis by using the factor analysis method to eliminate the correlation and overlaps between the nine factors, and derives its main influencing factors are the increase the value of two industries. Then, using the shift-share analysis method to analyze Tianjin service industry internal structure, and combining the structure and competitiveness deviation share, to adjust service industry internal structure optimization, and to find out the optimal structure of economic growth in Tianjin. Finally, it makes a regression analysis between the service industry internal structure optimization and economic growth in Tianjin, and makes a linear model of economic growth and structural change in the service sector, and makes predictions. Compared to the structure optimization of the growth rate of before and after optimization, it found that optimized internal structure has greatly improved the economic growth of services. Through the above analysis, we found the facing problem with the structure and development of service industry in Tianjin, and put forward policy economic development in Tianjin.
