城市价值链功能分工与企业创新:来自企业专利的证据

Urban Value Chain Functional Division of Labour and Firm Innovation:Evidence from Corporate Patents

本文通过识别中国城市中微观经营主体的主要功能测算各地区的城市功能分工,继而基于专利数据考察城市功能分工对企业创新的影响和作用机理。研究发现,城市功能分工能够显著促进企业创新,这背后的机制在于,城市功能分工能够促进区域内产业链完整和协同、提高企业供应链稳定性以及拓展企业贸易网络,并且城市功能分工有助于企业知识突破行政边界,在更大地理范围内传播。此外,城市功能分工对企业创新的影响会由于城市间距离、行业属性以及企业业务覆盖度的不同而存在差异。随着市场可达性和中心城市首位度的提高,城市功能分工对企业创新的提升作用趋于增强。本文为中国通过构建优势互补的区域经济布局培育企业创新的新动能提供了参考。

This paper assesses the urban functional division of labour in various regions by identifying the primary functions of micro-firms in Chinese cities,and then examines the impact and mechanism of the urban functional division of labour on firm innovation based on patent data.The study finds that the urban functional division of labour can significantly promote corporate innovation.The underlying mechanism is that the urban functional division of labour can enhance the integrity and synergy of the industrial chain within the region,increase the stability of corporate supply chains,and expand corporate trade networks.The urban functional division of labour also facilitates the transcendence of business knowledge across administrative boundaries,spilling it over a wider geographical range.The impact of the urban functional division of labour on corporate innovation may also vary due to differences in intercity distance,industry attributes and corporate business coverage.With the improvement in market accessibility and the prominence of central cities,the role of the urban functional division of labour in promoting corporate innovation tends to strengthen.This paper provides guidance for China to cultivate new drivers of corporate innovation by building a regional economic design with complementary advantages.
