摘要
城市规模是否会影响企业的研发创新行为呢?文章采用世行企业微观数据(2012)探究了城市人口规模对我国制造业企业研发创新行为的影响,并对微观机制进行实证检验。回归结果显示,在控制了相关的企业特征、城市特征、行业特征等因素后,城市人口规模显著地促进了制造业企业创新倾向、企业创新支出和企业创新支出占销售收入比重,稳健性检验支持这一结论。微观机制检验表明,提高城市人口中高技能人才比例有助于企业的研发创新,而非正规竞争程度较低和企业家经验不足会弱化城市人口规模对企业研发创新的促进作用。
Based on the data of 2012 World Bank Business Environment and Enterprise Performance Survey of Chinese Manufacturing firms, this paper empirically tests the effect of city size on manufacturing firm’s R&D innovation in China.It concludes that after controlling the related city、firm and industry characters, city size significantly promotes firm’s R&D innovation decision probability、expenditure and the ratio expenditure/sales. Besides, this positive relation holds with different sub-samples and overcoming the endogeneity. Further more, higher high-skilled labor density will promote fims’ innovation. While the weaker informal competition and less entrepreneurship is, the effect that city size has on R&D innovation will be weakened.
