基于POI数据的东北地区上市公司企业家精神时空演化特征及机理
Temporal and Spatial Evolution Characteristics and Mechanism of Entrepreneurship of Listed Companies in Northeast China Based on POI Data

培育与弘扬企业家精神对于推动企业创新发展与区域产业转型升级至关重要。本研究基于演化经济地理视角，利用熵权法、标准差椭圆、核密度等方法测度与分析了东北地区2009~2021年上市公司企业家精神，并通过双向固定效应模型探究其影响机理，结果表明：1) 研究期内东北地区城市企业家精神均数整体呈现增长趋势，但上市公司数量增长与企业家精神发展并不同步；2) 东北地区上市公司企业家精神时空分布表现出由散点状分布向集群分布的演化特征；3) 东北地区企业家精神格局呈现出在南北方向发散、东西方向上收敛、热点区域逐渐向南转移的趋势；4) 上市公司内部环境因素与外部环境因素对企业家精神产生显著影响。基于此，为东北地区政府宏观调控和上市公司战略决策提出建议。
Cultivating and promoting entrepreneurship is crucial to promoting the innovation and development of enterprises and the transformation and upgrading of regional industries. Based on the perspective of evolutionary economic geography, this study uses the entropy weight method, standard deviation ellipse, kernel density, and other methods to measure and analyze the entrepreneurship of listed companies in Northeast China from 2009 to 2021 and explores its influence mechanism through the two-way fixed-effect model. The results show: 1) During the study period, the average entrepreneurial spirit of cities in the Northeast generally showed a growth trend, but the growth in the number of listed companies was not synchronized with the development of entrepreneurial spirit; 2) The spatiotemporal distribution of entrepreneurship of listed companies in Northeast China shows the characteristics of evolution from scattered distribution to cluster distribution; 3) The pattern of entrepreneurship in Northeast China shows a trend of divergence in the north-south direction, convergence in the east-west direction, and the gradual shift of hot spots to the south; 4) The internal and external environmental factors of listed companies have a significant impact on entrepreneurship. Based on this, this paper puts forward suggestions for the macro-control of the government in Northeast China and the strategic decision-making of listed companies.
