京津冀上市公司对区域产业结构影响的空间计量分析

The Spatial Econometric Analysis of the Impact of the Listed Companies in Beijing-Tianjin-Hebei Region on Regional Industrial Structure

上市公司是区域经济发展中最富活力和制度优势的微观经济实体,对现代区域经济发展发挥着日益显著的作用。京津冀区域经济要协同发展,区域产业结构要优化,区域内上市公司要发挥带动作用。本文采用2003~2016年京津冀十三市的面板数据,在验证通过京津冀十三市产业结构存在空间自相关性的基础上,构建空间杜宾模型进行上市公司对区域产业结构作用关系的实证研究。实证结果表明,目前京津冀区域产业结构发展水平差距较大,未能形成有效的产业协同;总资产对区域产业结构升级呈现负效应,而上市公司的数量、投融资数额、上市公司产业结构层次系数对区域产业结构升级有促进作用。本文在研究基础上,从上市公司角度提出了促进区域产业结构优化升级的相关政策建议。

Listed companies are microeconomic entities with the most vitality and institutional advantages of regional economic development,playing an increasingly significant role in the modern regional economic development. Beijing-Tianjin-Hebei regional economy need coordinated development,and regional industrial structure should be optimized,the regional listed companies should play a leading role. Based on the panel data of Beijing-Tianjin-Hebei thirteen cities from 2003 to 2016,on the basis of validating the spatial autocorrelation of the industrial structure of the thirteen cities of Beijing,Tianjin and Hebei,this paper constructs the Spacial Dubin Model to carry out the relationship between listed companies and regional industrial structure. The results show that the gap of the level of industrial structure development between Beijing,Tianjin and Hebei is large and the effective industrial cooperation is not formed. The total assets have a negative effect on the upgrading of regional industrial structure,and the number of listed companies,the amount of investment and financing,the industrial structure hierarchical coefficient of listed companies have positive effects on the upgrading of regional industrial structure. On the basis of research,this paper gives the relevant policy recommendations of promoting regional industrial structure optimization and upgrade from the perspective of listed companies.
