经济集聚对产品质量升级的影响效应研究

Research on the Effect of Economic Agglomeration on Product Quality Upgrading

利用2010—2016年合并后的中国海关进出口数据库和工业企业数据库测算企业-产品-年度层面的质量,构建计量模型进行中国经济集聚对企业产品质量升级影响的实证检验。研究结果发现经济集聚程度的提高有助于提升中国企业产品质量。企业通过集聚到特定区域更加靠近劳动力、供应商、消费者和交通枢纽,降低了企业在用工、物流和推广方面的成本,使企业有更多的资源用以升级产品质量。同时,理清了经济集聚影响产品质量升级的作用机制,集聚所带来的效率提升和边际成本下降促进了产品质量升级。

Using the merged China Customs import and export database and industrial enterprise database from 2010 to 2016 to calculate the quality at the enterprise product annual level,An econometric model was constructed to empirically test the impact of China’s economic agglomeration on the upgrading of enterprise product quality.The results show that the improvement of economic agglomeration helps to improve the product quality of Chinese enterprises.By gathering in specific areas and getting closer to labor,suppliers,consumers and transportation hubs,enterprises reduce the cost of employment,logistics and promotion,So that enterprises have more resources to upgrade product quality.At the same time,it clarifies the mechanism of economic agglomeration affecting product quality upgrading.The efficiency improvement and marginal cost reduction brought by agglomeration promote product quality upgrading.
