辽中南城市群基础设施投资对产业结构的影响

Influence of Infrastucture Investment on the Industrial Structure of Urban Agglomeration in Central and Southern Liaoning

通过计算区位熵和泰尔指数、构建计量经济学模型来研究辽中南城市群产业结构的特点及基础设施投资对产业结构的影响,并与京津冀城市群对比。结果显示:①辽中南城市群第一、二产业集聚程度较高,但第三产业的集聚程度较低。②从产业合理度来看,其第一、三产业的产业结构合理度较高且较稳定,而第二产业结构不尽合理。③其产业结构与能源、交通及通讯基础设施投资有关,不同类型基础设施对产业结构影响侧重不同。

By calculating the location entropy and Theil index and constructing the econometric model,this paper studies the characteristics of industrial structure and the impact of infrastructure investment on industrial structure of urban agglomeration in central and southern Liaoning,and compared with Beijing,Tianjin,Hebei urban agglomeration.The results show that:①The agglomeration degree of the first and second industries in the urban agglomeration of central and southern Liaoning is relatively high,but the agglomeration degree of the tertiary industry is low.②From the perspective of industrial rationality,the industrial structure of the first and third industries is reasonable and stable,but the structure of the secondary industry is not reasonable.③Its industrial structure is related to investment in energy,transportation and communication infrastructure,and different types of infrastructure have different impacts on industrial structure.
