本文基于北京市、天津市和河北省2006年~2022年的面板数据,利用超越对数生产函数的随机前沿分析法构建模型,通过测算京津冀地区的经济增长效率,来分析影响经济增长效率的因素并提出相应的政策建议。结果表明,京津冀地区三地经济增长效率近乎相同,对比各年份发现,北京市经济增长效率比较稳定,天津市经济增长效率波动较大,其中经济增长效率在2006年至2015年间明显下降,河北省经济增长效率稳步提升。经济增长效率的变化主要源于资本存量和劳动力投入,结合效率损失模型发现,研发强度、城镇化水平和产业聚集会对经济增长效率的提升起促进作用,而对外开放程度和政府干预会对经济增长效率的提升起抑制作用。Based on the panel data of Beijing, Tianjin and Hebei Province from 2006 to 2022, this paper uses the stochastic frontier analysis method of translog production function to construct a model, calculates the economic growth efficiency of Beijing-Tianjin-Hebei region, analyzes the factors affecting the economic growth efficiency and puts forward corresponding policy suggestions. The results show that the economic growth efficiency of the three regions in the Beijing-Tianjin-Hebei region is almost the same. Compared with each year, it is found that the economic growth efficiency of Beijing is relatively stable, while that of Tianjin city fluctuates greatly. The economic growth efficiency of Tianjin City decreased significantly from 2006 to 2015, while that of Hebei Province increased steadily. The change in economic growth efficiency is mainly due to capital stock and labor input. Combined with the efficiency loss model, we find that R&D intensity, urbanization level and industrial agglomeration will promote the improvement of economic growth efficiency, while the degree of opening up and government intervention will inhibit the improvement of economic growth efficiency.
