服务业集聚、空间溢出与经济增长质量--基于中国省际空间面板杜宾模型的经验研究

本文基于2000－2013年中国省际面板数据，采用空间杜宾模型研究服务业集聚及其空间溢出对经济增长质量的影响，发现多样化服务业集聚对本省份和邻近省份的经济增长质量作用为正，服务业内竞争对本省份的经济增长质量影响不显著，但对邻近省份具有负作用，专业化集聚对本省份和邻近省份的影响均不显著；稳健性分析表明以上结论稳健且东部地区在服务业集聚提升经济增长质量方面具有区位优势。针对可能存在的空间分割，以各省会为圆心、每20 km或10km 进行累加形成距离带并对空间溢出进行估算，表明服务业集聚的空间溢出存在空间边界。

Service Agglomeration,Spatial Spillovera nd Quality of Economic Growth---An Empirical Analysis Based on Spatial Dubin Model

The paper establishes Spatial Durbin Model to estimate the impact of service industry agglomeration on the quality of economic growth.The result indicates that diversified agglomeration of service industry has a positive effect on im-proving the quality of economic growth, but the role of enterprise competition and specialized agglomeration is not significant. Furthermore, a robust test finds that the agglomeration of service industry has a positive effect on not only the province itself but also the adjacent regions.Enterprise competition, in contrast, plays a negative role.Additionally, the eastern areas have the ad-vantage in terms of location.Ultimately, in view of the possible oversize of sample space, the article makes an estimate of the spatial spillover centering on the provincial capital and forming the distance belt by accumulation for every 20 or 10 kilometers. The estimate shows that the spatial spillover of service industrial agglomeration is positive with the existence of space boundary.
