东北三省战略性新兴产业企业进入与退出的时空格局及影响机理

Spatiotemporal Patterns and Influencing Mechanism of the Entry and Exit of Enterprises in Strategic Emerging Industries in the Three Northeastern Provinces

基于企业数据,结合核密度估计、标准差椭圆和地理探测器方法,分析2009—2022年东北三省战略性新兴产业企业进入和退出的时空格局演变及影响机理。结果表明:(1)东北三省战略性新兴产业企业进入与退出均具有较强的中心城市指向性。(2)资源型城市的产业发展呈现渐进式稳定发展态势。(3)企业进入空间演化形成“多核心-外围”格局,退出形成“单核心-多核心-外围”演化格局,进而影响重心转移轨迹,进入重心逐渐南移,退出重心逐渐北移。(4)产业、区域和政策关联的共同作用塑造了东北三省战略性新兴产业企业进退格局。

Based on enterprise data,combined with kernel density estimation method,standard deviation ellipse and geodetector,this paper analyzed the evolution of spatio-temporal patterns of entry and exit of firms in the strategic emerging industries in the Three Northeastern Provinces and the mechanism of influence from 2009 to 2022.The conclusions reveal:(1)The entry and exit of enterprises in the strategic emerging industries of the Three Northeastern Provinces are strongly oriented towards central cities.(2)The industrial development of resource-based cities shows a gradual and stable progression.(3)The spatial evolution of enterprise entries has formed a“multi-core-periphery”pattern,while exits have developed a“single-core-multi-core-periphery”evolutionary pattern,thereby affecting the trajectory of the gravity center shift.The entry gravity center gradually moves southward,whereas the exit gravity center gradually shifts northward.(4)The combined influence of industry,regional dynamics,and policy shapes the entry and exit patterns of enterprises in the strategic emerging industries of the Three Northeastern Provinces.
