| In recent years,with the continuous development of economy,industrial agglomeration has developed into an important economic phenomenon,which has attracted more and more scholars' attention.Generally,the external economic benefits arising from industrial agglomeration are important sources for creating and maintaining competitive advantage.The specialization and diversification conditions provided for enterprises can promote enterprises to improve their management level and promote the improvement of profit margins of agglomeration enterprises.In addition,with the rapid development of science and technology and the increasing pressure of global market competition,the innovation capability of enterprises is becoming more and more important.Enterprises in order to occupy a certain market share in the new market,we must continue to enhance the capability of independent innovation.Therefore,to vigorously promote industrial agglomeration and encourage enterprises to increase innovation input are of great significance to the economic development of our country and the growth of enterprises.This paper examines the impact of industrial agglomeration and innovation on the profitability of enterprises by building an integrated empirical analysis framework and using the panel data of industrial enterprises above designated size in China from 2003 to 2007.The article is divided into six parts: The first chapter is introduction.The background,significance,research ideas,contents and methods of the topic are introduced,and some possible innovations and shortcomings of the article are put forward.The second chapter is related theory and literature review.In this part defines the concept of industrial agglomeration and innovation,summarizes the relevant theories about industrial agglomeration and innovation,and reviews relevant researches on industrial agglomeration and innovation.The third chapter is the characteristic fact.It introduces the measurement methods of industrial agglomeration,innovation and enterprise profit rate,and uses the data to show the characteristics of China's industrial agglomeration,innovation and corporate profit rate from different levels.The fourth chapter is the theoretical mechanism of industrial agglomeration,innovation and enterprise profit margin.Based on the previous studies,this paper constructs the mechanism of the influence of industrial agglomeration and innovation on the profit rate of enterprises,and puts forward four hypotheses.The fifth chapter is the empirical analysis of industrial agglomeration,innovation and enterprise profit margin.This chapter firstly constructs a balanced panel model that industrial agglomeration and innovation affect the profit rate of the enterprise.Empirical analysis of the four hypotheses proposed in the previous chapter by using the data of industrial enterprises above the designated size in our country,tests the rationality of the hypothesis,and explores the effect of industrial agglomeration and innovation on enterprise profit margin.Further,the article also classifies the business samples,examines the heterogeneity of the enterprise profit rate caused by industrial agglomeration and innovation,and tests the above results robustly.The sixth chapter is the conclusion and policy suggestion.Summarize the research of the full text,and put forward corresponding countermeasures and suggestions according to the conclusion of the research.Through theoretical analysis and empirical test,this paper draws the following conclusions:(1)Use the industry agglomeration indicators and related industry agglomeration indicators for empirical test,The results show that the industrial agglomeration and the related industrial agglomeration increase will significantly improve the corporate profitability,And the effect of industrial agglomeration on the promotion of corporate profit margin is greater than the contribution of relevant industrial agglomeration to corporate profitability.This conclusion proves the correctness of Hypothesis 1.(2)The use of specialized agglomeration indicators for empirical testing,it is found that the estimated coefficient of the specialization agglomeration is significantly positive,indicating that the higher the degree of specialization is,the greater the promotion effect on the profit rate of the enterprise,which verifies the rationality of Hypothesis 2.(3)Empirical test using regional agglomeration indicators found that the estimated coefficient of regional agglomeration was significantly positive,indicating that the increase of agglomeration in the region will promote the improvement of profit margins of enterprises;The estimated results of the agglomeration in adjacent areas are not significant,indicating that the influence of agglomeration in adjacent areas on the profit margin of enterprises is negligible;The estimated coefficients of agglomeration in other regions are significantly negative,indicating that the increase of industrial agglomeration in other regions will have a negative impact on the profitability of local enterprises.The above analysis shows that the impact of industrial agglomeration on the profitability of enterprises is highly regionalized.The effect of industry agglomeration on corporate profitability in a certain industry is weakened with the increase of geographic distance,which verifies the correctness of Hypothesis3.(4)The measurement results show that all the estimated coefficients of innovation are significantly positive,indicating that innovation can obviously promote the improvement of corporate profit margin.This conclusion verifies the rationality of Hypothesis 4.(5)According to the types of enterprises,the types of industries they belong to,the export status and the regional distribution,this paper classifies the enterprises' samples,and examines the heterogeneity of industrial agglomeration and innovation on the corporate profitability.The study found that industrial agglomeration and innovation will significantly increase the profitability of foreign-funded and private-owned enterprises,high-tech industry enterprises and enterprises in the eastern region.In addition,the impact of industrial agglomeration and innovation on the profitability of enterprises also varies with the export status and export intensity.To sum up,in order to give full play to the role of industrial agglomeration in promoting the profitability of enterprises,the government should follow the law of industrial development and scientifically formulate plans according to the existing industrial bases,refine the industrial classification,expand the industrial scale,promote industrial agglomeration and improve endogenous growth momentum.In addition,the government should also create a social environment that encourages innovation,formulate preferential policies to enhance the willingness of enterprises to innovate,and make full use of the promotion effect of innovation on the profit rate of enterprises. |
