生产性服务业集聚对制造业生产效率的外溢效应及其衰减边界——基于空间计量模型的实证分析

The Spatial Spillover Effect and Regional Damping Boundary of Productive Services Agglomeration on Manufacturing Productivity:Empirical Research Based on Spatial Econometric Model

本文利用全国230个城市数据,以经济地理距离作为空间权重矩阵,采用空间计量模型实证分析了生产性服务业空间聚集对制造业生产效率提升的空间外溢效应及衰减边界。实证结果表明,生产性服务业空间聚集对制造业生产效率提升的空间外溢效应表现较为明显,并且这种空间外溢效应会存在具有空间衰减特征的地理边界,在200公里以内为空间外溢的密集区域,500公里为空间外溢的"半衰"距离,省界对空间外溢效应的发挥具有一定的阻碍作用。

With data collected from 230 cities in China, this paper analyzes the spatial spillover effect and its regional boundary of producer services＇ spatial aggregation on the manufacturing productivity. Research takes advantage of spatial econometric model in which the economic geographic distance is a spatial weight matrix. The empirical result shows that the space spillover effect is significant and there is a certain regional damping boundary of the spatial spillover effect. We find out that the dense area of spatial spillover is within 200 km and 500 km is the halving-effect distance. Provincial boundaries have certain negative effects on space spillover effect.
