政府行为下创新要素流动及其空间溢出效应研究

Research on the Flow of Innovation Factors and the Spatial Spillover Effect under Government Behavior

基于2000-2018年中国内地31省市面板数据,采用固定效应分析法探讨政府行为与创新要素流动的内在机理,运用空间杜宾模型探究两者之间是否存在空间溢出效应。结果发现:就全国而言,地方政府竞争行为对R&D人员和R&D资本要素流动存在倒U型影响,且地方政府竞争与政府支持、政府支持与政府房地产投资偏好行为可以协同发力促进创新要素流动;另外,地方政府竞争和政府支持能够促进周边地区创新要素流动,而政府房地产投资偏好仅能影响周边地区R&D人员流动。在分区域研究中,东部地区3种地方政府行为对创新要素流动均存在倒U型影响,中部地区政府房地产投资偏好行为发挥倒U型作用,而政府竞争和政府支持行为发挥正U型作用;地方政府行为协同对中西部地区创新要素流动发挥正向促进作用,但在东部地区影响甚微。

Based on the panel data of 31 provinces and cities across the country from 2000 to 2018,the fixed effect analysis method is used to explore the internal mechanism of government behavior on the flow of innovative elements,and the spatial Dubin model is used for further analysis to explore the relationship between the two is there a spatial spillover effect?The research found that:as far as the whole country is concerned,local government competition behaviors present an inverted U-shaped characteristic to the flow of R&D personnel and R&D capital elements,and local government competition and government support,government support and government's real estate investment preference behaviors can work together to promote the flow of innovative elements,further research also found that local government competition and government support can promote the flow of innovative elements in surrounding areas,while government's real estate investment preferences can only affect the flow of R&D personnel in surrounding areas.In the sub-regional study,the three types of local government behaviors in the eastern region all have an inverted U-shaped feature on the flow of innovation factors.In the central region,only government's real estate investment preference behavior plays an inverted U-shaped role,while government competition and government support behaviors play a positive"U"-shaped role trend;the synergy between local government actions plays a positive role in promoting the flow of innovative elements in the central and western regions,but has almost no impact in the eastern region.
