| With the development of economy,regional integration has become the basis for mutual cooperation,complementarity,and win-win cooperation.Industrial agglomeration is an important form of development for industrial organizations and has become increasingly prominent in the process of regional economic integration.The role.In 2015,the country confirmed the major policy of the coordinated development of Beijing,Tianjin and Hebei,and the construction of Beijing-Tianjin-Hebei integration was formally put on the agenda.The current situation of the Beijing-Tianj in-Hebei region is unique,and the uneven distribution of industries in the region is the main obstacle to the suppression of regional coordinated development.In this context,this paper empirically analyzes the impact of industrial agglomeration in the Beijing-Tianjin-Hebei region on the economy,and provides constructive opinions on industrial restructuring through empirical results.In view of the research issues in this paper,the article is divided into five parts and discusses two key issues to be solved.One is to choose a suitable method to measure the level of agglomeration in the Jing-Jin-Ji region,and the other is to measure the degree of industrial agglomeration to the economy of Beijing-Tianjin-Hebei area.Impact.This article refers to the existing literature and summarizes the method of measurement of industrial agglomeration.The degree of agglomeration of the three major industries in Beijing,Tianjin,and Hebei is measured by market concentration,location entropy based on the national perspective,and spatial Gini coefficient,and then based on Beijing-Tianjin-Hebei The location entropy of the perspective measures the degree of agglomeration of the three major industries in the 13 cities within the Beijing-Tianjin-Hebei region.In order to study the specific impact of Beijing and Tianjin on Hebei Province,in the calculation of the location entropy of 11 cities in Hebei Province,the article divided 11 cities into two groups,A and B according to geographical proximity to Beijing and Tianjin.Group A is near Beijing.In the city of Tianjin,Group B is a city far from Beijing and Tianjin.After calculating the location entropy,we use the improved Cobb-Douglas production function to establish a model of the effect of industrial agglomeration on economic growth.We use econometrics panel analysis to analyze the data and draw conclusions from an empirical perspective.Finally,the paper finds that Beijing and Tianjin have a great role in promoting the development of the secondary industry in neighboring cities,but they have an inhibitory effect on the development of the tertiary industry.As a whole,the impact of the agglomeration of the secondary industry on the economy is no longer significant,and adjustment of the industrial structure is of the highest priority.The labor input in the primary industry and the secondary industry should be reduced,the labor force in the tertiary industry must be increased,and the quality of the workforce must be upgraded as soon as possible.It is not confined to increasing the number to promote industrial development.Capital investment can promote industrial development and can increase capital investment. |
