Empirical Analyze Of The Differences In Regional Economic Growth And Convergence In The Beijing-Tianjin-Hebei

The differences of regional economic growth has becomes one of the hot research problems of regional economics. Moderate regional economic growth differences contribute to the rapid economic development, but beyond a certain limit will bring about a series of salient economic, social, ecological problems. As one of the three urban agglomerations, Beijing-Tianjin-Hebei is also be the third growth pole of China economic. The cooperation development of Beijing-Tianjin-Hebei is highly emphasized by governments at all levels, which has been risen to a national strategy, in February 2014. Although the researchers have made some achievements, such as the integration of industry, factor market and public services, the regional differences of economic development will hinder the development of regional economic collaboration. Therefore, studying the differences in economic growth of Beijing, Tianjin and Hebei has a special significance from the perspective of convergence and divergence.Under the background of the cooperation development of Beijing-Tianjin-Hebei, this thesis specially selects Beijing, Tianjin, Hebei and 11 prefecture-level cities as the research object, subsequently the differences in regional economic growth and convergence in the region are introduced from different perspectives, based on the non-balanced theory, the convergence theory and the research results at home and abroad. More specifically, the statistical analysis method is adopted in the study of the the changes differences in economic growth over the 2001-2014, from the total economy and changes in the industrial structure; The convergence theory and test methods Barro and Sala-I-Martin proposed, are adopted in the analysis of absolute convergence and conditional convergence from 1995-2014, and also make a quantitative analysis of the influencing factors.First, this paper use the standard deviation and coefficient of variation measure the absolute and relative differences of Beijing-Tianjin-Hebei during 2001-2014. The analysis indicate that there are distinct regional economic divergence and the industrial structure convergence in Beijing-Tianjin-Hebei. On this basis, from the perspective of economic convergence, using the classic convergence model to test the convergence, the results showed that in 1995-2014, the region occurred σ- convergence and absolute b-convergence, while there are no σ- convergence and absolute b-convergence in 2001-2004. Then, the investment rate, human capital, openness and industry structure are selected as a single steady state factor to do Conditional convergence analysis. It found that the rate of investment rate, human capital, openness, the proportion of secondary industry structure coefficients are positive, promoting urban economic growth. However, the proportion of tertiary industry structure coefficient is negative, hindering conditional convergence in economic growth of Beijing-Tianjin-Hebei. Finally, based on the above eoretical and empirical analysis, this paper gives suggestions, in order to promote the cooperation development of Beijing-Tianjin-Hebei: Promote the sound and rapid development of Hebei; Improve the free flowing of production factors; Optimize the regional industrial structure.
