摘要
企业是科技创新活动的重要主体,提高企业技术创新能力是激发区域创新活力、建设创新型国家的有效途径。本文利用2011-2018年上海市科技企业微观数据,基于多时点双重差分法,实证研究了城市内部企业迁移对企业技术创新绩效的促进效应,并验证了这种效应的企业行业、规模、所有制、区位异质性。研究发现,整体而言,城市内部企业迁移行为对其技术创新绩效有显著的促进效应,表现为企业迁移后知识产权申请数较迁移前平均增长6.4%。分样本研究表明,迁移对于不同行业的企业影响程度不同,服务业、高新技术企业的迁移效应分别强于制造业和非高新技术企业;将样本划分为微型、小型、中型和大型后研究发现,企业规模越大,企业迁移的技术创新效应越强;迁移对非国有企业的技术创新促进效应更强,对国有企业技术创新绩效无明显提高;此外,向郊区迁移、向开发区迁移对企业技术创新的促进效应更强。更换估计方法为倾向评分匹配模型和精确断点回归模型后,结果依然稳健。
Relocation is an adjustment strategy for firms to seek the optimal business location,which has been a classic topic in the field of regional economics.Relevant studies have investigated the spatial patterns and influencing factors of firm relocation and its impact on economic benefits,while few have discussed the effects of firm relocation on innovation performance.Based on the theoretical analysis of the relationship between firm relocation,firm characteristics and innovation performance,the hypotheses proposed are as follows:there is a positive correlation between firm relocation and technological innovation performance;the positive effect on manufacturing and non-high-tech firms is lower than that on service industry and high-tech firms;the effect on large firms is higher than small firms;the effect of non-state-owned firms is higher than state-owned firms;the effect on firms moving from urban areas to suburbs is higher than that of moving from suburbs to urban areas;the effect on firms moving into special economic zones is higher than that on firms moving out of zones.This paper used the annual survey data on technology firms collected by the Shanghai Science and Technology Committee(STCSM) during the period of 2011-2018,and the staggered difference-in-difference model.The dependent variable is the amount of intellectual property applications of firms in each year,and the independent variable is whether the firm had moved in each year.The model also controls firm characteristics including RD labor,RD expenditure and its quadratic term,income,asset,age,high-tech certification,firm fixed effects and time fixed effects.The model has satisfied the parallel trends assumption.The research results confirmed the hypothesis that firm relocation within Shanghai has a positive effect on their technological innovation performance,and investigates the heterogeneity of promoting effect.The main conclusions of the study are as follows:Firstly,regional environment affects the innovation behavior of firms,so firms relocate to
