外资企业空间集聚与内资企业出口产品质量——基于270个城市的空间动态面板数据模型

The Spatial Agglomeration of Foreign Enterprises and the Quality of Export Products of Domestic Enterprises : Based on the Spatial Dynamic Panel Data Model of 270 Cities

以地级以上城市为基本空间单位,使用详细的外资企业空间分布数据,构建了外资企业空间集聚指标,以集中反映外资企业的集聚效应和技术溢出效应;在此基础上运用系统广义矩估计的空间动态面板数据模型考察了外资企业空间集聚对内资企业出口产品质量的影响效应。研究发现在270个城市,内资企业出口产品质量具有空间溢出性,对于空间相邻且经济差距较小的城市影响更大。外资企业就业集聚和销售收入集聚与内资企业出口产品质量之间总体存在倒U型关系,进一步研究发现这种倒U型关系主要出现在东部城市和大城市。

The paper takes county -level and the above cities as the basic spatial unit and ap- plies detailed spatial distribution data of foreign enterprises to construct spatial agglomeration index of foreign enterprises, aiming to well reflect the agglomeration effect and the technological spillover effect. Based on the analysis, generalized method of moments of spatial dynamic panel data model is used to investigate the influence of the spatial agglomeration of foreign enterprises on the quality of export products of domestic companies. Study shows that the quality of export products of do- mestic companies has spatial spillover effects in 270 cities, and the effect is stronger in adjacent cities with less economic gap. Both the employment agglomeration and sales income agglomeration of foreign enterprises have an inverted u - shaped relationship with export product quality of do- mestic enterprises, and further study proves that the inverted u - shaped relationship mainly ap- pears in the eastern cities and big cities.
