产业集聚提升了出口产品质量吗?——来自中国制造业企业的经验证据

Has Industrial Agglomeration Improved the Quality of Export Products?——Empirical Evidence from China's Manufacturing Enterprises

在构建产业集聚与出口产品质量理论模型的基础上,基于2000 2007年中国工业企业数据和海关贸易数据,采用需求方程反推法对企业出口产品质量进行测算,考察产业集聚对企业出口产品质量的影响。研究结果显示:在总体层次上,产业集聚对企业出口产品质量具有显著的促进作用;在区分企业类型后发现,产业集聚能够显著提升私营和外资企业、加工贸易企业、东部地区企业的出口产品质量,对国有企业、一般贸易企业、中西部地区企业出口产品质量的影响则较小。

Building the theoretical model of industrial agglomeration and export product quality,based on Chinese industrial enterprise data and customs trade data from 2000 to 2007,this paper measures the quality of enterprises＇ export products using demand equation regression inference method first,and then investigates the effects of industrial agglomeration on the quality of export products.The results show that industrial agglomeration has a significant promoting effect on the quality of China＇s export products.Furthermore,considering ownership,trade type and region distribution of enterprises,we also find that industrial agglomeration can significantly improve the quality of export products of private enterprises and foreign enterprises,processing trade enterprises and enterprises in east China,while has little impact on the quality of export products of stateowned enterprises,general trade enterprises and enterprises in Midwest China.
