利用1999-2011年我国制造业15个行业数据,将垂直专业化、产业空间集聚与制造业生产率置于统一的框架下,分析垂直专业化与产业空间集聚的相互作用对制造业生产率的影响。结果显示:垂直专业化分工的加深对我国全要素生产率(TFP)增长的作用不是很明显,但对技术效率的影响要大于对TFP增长的影响程度;产业空间集聚明显促进了TFP增长,表明产业空间集聚在一定程度上提高了产业资源的利用效率;可能由于我国处于垂直专业化分工和集聚的产业主要是劳动密集型等相对低端产业,所以垂直专业化分工和产业空间集聚的交互作用对TFP增长有相对的削弱作用。
Using the data of 15 industries in manufacturing industry in China from 1999 to 2011, the author puts the vertical specialization, industrial agglomeration and manufacturing productivity into a unified framework, and analyzes the influence of the interaction between vertical specialization and industrial agglomeration on manufacturing productivity. The results show that the deepening of the specialization of verticalization has a less significant effect on TFP growth in China, but the impact on technical efficiency is greater than the impact on TFP growth. Industrial agglomeration has obviously promoted the growth of TFP, indicating that industry The spatial agglomeration improves the utilization efficiency of industrial resources to a certain extent. It may be due to the fact that the vertical specialization and industrial agglomeration in China are relatively low-end industries such as labor-intensive industries, TFP growth has a relative weakening effect.
