本文以企业异质性框架为基础,从理论上探讨了经济活动集聚影响企业出口绩效的机制,在理论分析的基础上利用我国2002~2009年的企业微观数据进行实证分析。通过实证分析证实:我国制造业经济活动的集聚,显著提高了我国技术复杂度较高企业的出口绩效;分行业样本的估计结果显示,我国制造业中技术密集型行业经济活动的集聚对企业出口绩效的影响最大;从不同所有制结构样本的估计结果看,外资企业的集聚对出口绩效的影响最为明显,同时企业技术复杂度的增加对技术密集型行业集聚出口效应的发挥所产生的提升作用最大,其次为民营企业,对国有企业的提升作用最低。
Based on the enterprise heterogeneity framework, this dissertation explores the mechanism of agglomeration of economic activities that affects the export performance of enterprises based on the theory of enterprise heterogeneity. Based on the theoretical analysis, this paper uses the micro-data of enterprises in our country from 2002 to 2009 for empirical analysis. Empirical analysis confirms that the agglomeration of economic activities in manufacturing industry in our country significantly improves the export performance of enterprises with high technical complexity in our country. The estimated results of sub-sectors show that the agglomeration of economic activities of technology-intensive industries in manufacturing industry is not significant to the export of enterprises From the estimation results of different sample of ownership structure, the effect of agglomeration of foreign-funded enterprises on export performance is the most obvious. At the same time, the increase of technical complexity of enterprises has the largest effect on the enhancement of agglomeration export effect of technology-intensive industries , Followed by private enterprises, which have the lowest promotion effect on state-owned enterprises.
