Industrial Structure Adjustment And Sustainable Economic Growth

As the economic center in bohai rim region, Tianjin is changing from traditional industry city to the modern manufacturing base. During the rapid economic growth period in Tianjin, the Twelfth Five-year Plan also pointed to speed up the adjustment of industrial structure to achieve the sustainability and stability of economic growth. Therefore, through the empirical research of the industrial structure and economic growth in Tianjin, this article tries to find that how the industrial structure influences the economic growth, especially all the elements of the three industries, so as to make appropriate industrial structure adjustment policies.In order to study the relationship bebween industrial structure and economic growth, in the review of the research of scholars both at home and abroad, this article mainly takes the theory of structurlism. According to Feder model, this paper derived the structurlism growth model of the three industries, and analyzed how the elements of the three industries influence the economic growth; Second,from the analysis of the industrial structure and economic growth situation currently, the paper got that the industrial structure of tianjin is still "231" mode, the third industry is in stagnation in recent years, but is absorbing surplus labor, the role of science and technology gradually improved; Moreover,the paper empirically analyzed the contribution of the three industries factors to the growth of economic with panel data model in Tianjin, Beijing and Hebei province and estimated the marginal productivity of the three industries elements, in tianjin that the influence of capital investment to economic growth is negative in second industry, the first industry and the third industry are positive, in first industry the labor impact to economic growth is negative, the second and third industry are positive, the impact of science and technology is great to economic growth. Through the comparison of the marginal factor productivity in three areas, the paper discovered that Tianjin had similar industrial structure with Beijing, and had a significant difference with Hebei province,so different industry structure adjustment policies should be given for different area. Finally, according to the conclusion of the empirical analysis, the article made specific suggestions to three industries.
