| Facing the current complex international trade environment,promoting high-quality development of trade is an inevitable trend of China’s foreign trade development.Under the background that the "low price strategy" is difficult to maintain the stable growth of foreign trade,the quality of export products has become a new advantage in the international trade competition.Manufacturing enterprises are the micro subjects to improve the quality of export products.In the growth process of manufacturing enterprises,industrial agglomeration phenomenon occurs simultaneously and positively promotes the development of enterprises.In the process of enterprise operation,financing constraints limit the development of enterprises to some extent.Related research has shown that industrial agglomeration can affect the enterprise export product quality and financing constraint level,based on the literature,grasp the research status,this paper hopes to further through theoretical analysis and empirical analysis of industrial agglomeration positive effect of export product quality can restrain the negative financing constraint on the quality of export products.This paper first analyzes the intermediary effect of industrial agglomeration,export product quality upgrading and financing constraints at the the or eti cal level and puts forward the hypothesis,Then,the two-way fixed effect model and mediation effect model based on the matching data of China industrial enterprise database and China Customs database from 2006 to 2014,The results show that:(1)the overall quality of China’s export products shows an upward trend,The quality of export products of enterprises in the eastern regions is lower than that in the central and western regions,The quality of export products of general trade enterprises is lower than that of processing trade enterprises,The product quality of non-state-owned enterprises is lower than that of state-owned enterprises;(2)There is a significant inverted "U"-type non-linear relationship rather than a simple linear relationship between industrial agglomeration and the quality of enterprise export products,At the same time,according to the analysis of the enterprise agglomeration degree during the sample period,At present,China is in the stage of industrial agglomeration is conducive to the quality upgrading of export products;Industrial agglomeration plays a greater role in promoting the quality of export products of enterprises and processing trade enterprises in eastern China,Moreover,the industrial agglomeration only has a significant inverted"U" type non-linear relationship with the export product quality of enterprises in eastern China,general trade enterprises and non-state-owned enterprises;(3)Financing constraints is an important way for industrial agglomeration to promote the quality upgrading of export products,The mediation effect of the financing constraint is manifested as the partial mediation effect,Further investigation revealed that,The mediation effect was significantly different among different types of enterprises.The intermediary effect of financing constraints is more obvious in enterprises,processing trade enterprises and non-state-owned enterprises in the central and western regions.In addition,the intermediary effect of financing constraints appears in the enterprises with high level of financing constraints.Finally,based on the research conclusion,this paper puts forward policy suggestions for the industrial development in China by strengthening the top-level design,providing policy support,strengthening the "environment" construction,strengthening the foundation of industrial agglomeration,preventing and building a diversified industrial development system. |
