交通基础设施对生产性服务业发展的溢出效应——基于省际的空间计量模型分析

The Spillover Effects of Transport Infrastructure on the Producer Services:A Spatial Econometric Analysis Based on the Provincial Data

生产性服务企业因其服务的专业化和即时化特点,倾向于在交通发达的城市集聚,本文基于2005~2015年省际的空间计量分析证实了上述结论,即交通基础设施对所在地区生产性服务业发展具有显著的正向促进作用。研究还发现:相邻地区的生产性服务业发展存在正向的空间溢出效应,并且这一溢出效应主要发生在市场规模和经济发展程度相近的地区之间,地理上邻近性的作用相对较弱。这一结论一定程度上解释了部分地理位置相邻但市场规模和经济发展程度不同的地区间生产性服务业发展趋势出现分化的现象。通过对空间溢出效应的分解可以发现,交通基础设施对邻近地区生产性服务业发展存在正向的空间溢出效应,但全国层面的空间溢出效应较小,这与不同地区生产性服务业的发展阶段和溢出效应的差异有关,因此政府需要根据地区生产性服务业发展所处的阶段及发展潜力进行交通基础设施的投资和建设。

As the provider of professional and rapid response productive services,the producer service enterprises tend to cluster in the traffic developed area.The research based on 2005-2015 provincial spatial econometric confirms the above conclusion,namely,regional transportation infrastructure has significant positive influence on the development of local producer services.Furthermore,the development of producer services itself has a positive spillover effect on the adjacent regions,and the spillover effect mainly occurs between regions with similar market sizeand economic development level,while geographical adjacent is relatively less important.This conclusion can partly explain the divergence in the development of the producer services industry among regions that are geographically adjacent but with different market size and economic development.By decomposing the space spillover effect,the author finds the regional transportation infrastructure had weak positive spillover effect on the adjacent regions,which may be caused by the offset effect among different regions.Therefore,the government needs to invest and build the transportation infrastructure based on the development stage and potential of the regional producer services industry.
