摘要
本文以生产性服务业单独集聚和生产性服务业与制造业协同集聚两种集聚模式对制造业出口产品质量的差异化影响为研究切入点,在科学识别生产性服务业集聚与出口产品质量升级的基础上,运用面板数据模型进行多维检验分析。得到的研究结论主要有:(1)2004-2017年间我国制造业出口产品质量呈现“W”型变动趋势,金融冲击下出口产品结构调整和制造业高质量产品生产能力提升分别是两次增长出现的主要动因。(2)生产性服务业单独集聚和与制造业协同集聚两种集聚模式均有助于出口产品质量的提升,然而单独集聚模式下拥挤效应已经出现,使得单独集聚对制造业出口产品质量的作用效果呈现倒U型。(3)金融冲击会抑制生产性服务业集聚对出口产品质量提升作用的发挥,而税收冲击对集聚的作用效果无显著影响。
This article takes the two different modes of single agglomeration of producer services industry and co-agglomeration with manufacturing industry as the research entry point.After incorporating the production decisions of the producer service sector into the firm product quality heterogeneity model and constructing the theoretical relationship between the agglomeration of producer services industry and the quality of export products,this paper uses the panel data at the provincial level for empirical tests.The main conclusions are as follows:(1)The quality of China's manufacturing export products from 2004 to 2017 showed the W-type change trend,the adjustment of the export product structure after the financial shock and the improvement of the manufacturing capacity of high-quality products were the main reasons for the two growths.(2)The single agglomeration in producer services industry and co-agglomeration with the manufacturing industry are both conducive to the improvement of export product quality.However,the congestion effect has emerged under the single agglomeration mode,which makes the effect of single agglomeration on the quality of manufacturing export products an inverted U-shaped.(3)Financial shocks will inhibit the producer services industry agglomeration effect of improving the quality of export products,while tax shocks have no significant effect on agglomeration effects.
