| Under the theoretical framework of new economic geography,this paper focuses on the impact of transportation infrastructure on the industrial aggregation of Guangdong Province,and extends the center-periphery model from the scope of manufacturing to producer services,and according to the characteristics of Guangdong 's economic development.The collaborative research of manufacturing and producer services,the location advantages of central cities and the impact of informatization development on industrial agglomeration are the key research objects of this article.Secondly,this article innovatively establishes a relatively complete traffic evaluation system from the perspective of traffic accessibility as an important method to measure traffic development,which truly and accurately measures the level of traffic development in Guangdong Province,making the empirical results more authentic and credible.Then,this paper believes that the impact of transportation infrastructure on industrial agglomeration mainly depends on the cost effect and crowding-out effect brought by the improvement of transportation development level.When the cost effect is greater than the crowding-out effect,transportation infrastructure has a promoting effect on industrial agglomeration,and vice versa Not conducive to industry gathering.The empirical results of this paper show that:(1)transportation infrastructure significantly promotes the aggregation of manufacturing industries,but it has a squeezing effect on the aggregation of producer services;(2)the aggregation of manufacturing industries and producer services interacts with each other;(3)beads Compared with the non-Pearl River Delta,the triangle is more attractive to enterprises and is conducive to industrial aggregation;(4)The level of informatization development has a significant role in promoting the aggregation of producer services.Based on the above empirical results,this article proposes the following policy recommendations:(1)It is recommended to increase investment in transportation infrastructure and build a modern transportation system;(2)It is recommended to create suitable industries and supporting measures based on city positioning;(3)It is recommended to invest limited resources in the Pearl River Delta region to optimize the industrial development environment;(4)It is recommended to increase investment in 5G construction and use information technology to promote industrial development... |
