摘　　要：行政区边界地带经济发展落后,是中国实现共同富裕需要解决的重大问题。本文构建扩展的空间杜宾模型,经验研究省级行政边界通过屏蔽技术扩散对经济增长的抑制作用。我们基于2001—2013年的地级市面板数据,发现技术在城市间扩散。对于某城市,其毗邻的同省城市的技术进步率增加1个百分点,平均意义上会导致该市技术进步率增加0.313个百分点;其毗邻的外省城市的技术进步率增加1个百分点,平均意义上会导致该市技术进步率增加0.196个百分点。这意味着省界屏蔽了0.117个百分点(37.38%)的技术扩散。省界通过屏蔽技术扩散导致城市年经济增长率降低0.325个百分点。这一经济增速损失占平均增长率的2.50%。机制分析表明,方言和地方保护是省界屏蔽技术扩散的原因。本文结论表明,促进省际边界地带经济发展,需要打破各种妨碍技术扩散的政策壁垒。The less-developed status of economy in administrative border areas is a major problem that China has to resolve to reach common prosperity.This paper sets up an extended spatial Durbin model and empirically studies the inhibitory effect of provincial borders on economic growth through shielding technology diffusion.Based on the panel data of prefecture-level cities from 2001 to 2013,we find that technology spreads among cities.For a prefecture-level city,one percentage point increase in the technological progress rate of the adjacent cities in the same province leads to an average increase of 0.313 percentage points in the technological progress rate of the city,while one percentage point increase in the technological progress rate of the adjacent cities in other province only results in an average increase of 0.196 percentage points in the technological progress rate of the city.This implies that the provincial border shields technology diffusion by 0.117 percentage points(37.38%).This shielding effect of provincial border reduces the annual economic growth rate by 0.325 percentage points.This loss of economic growth rate accounts for 2.50%of the average growth rate.Mechanism analysis shows that dialect and local protectionism drive the shielding effect.According to our findings,in order to promote the economic development of provincial border areas,it is necessary to break down all kinds of policy barriers that hinder technology diffusion.
