中国制造业产业聚集对技术创新效率影响的实证研究——基于2005-2014年的省际面板数据

摘要

以区位熵作为中国各省市制造业聚集指数测度指标,基于规模报酬可变的Super-SBM三阶段DEA模型分析法,对中国各省市(除西藏)技术创新效率进行测算,并用2005-2014年省际面板数据研究产业聚集对技术创新效率的影响.结果显示,在控制对外开放程度和制度创新的条件下,产业聚集对技术创新效率呈正向影响;并且随着产业集聚程度的提高,技术创新效率呈现先递减、后渐增、再递减的发展态势,即产业聚集增长效应符合“倒N型”假说.%This paper,by taking the location entropy as the accumulation index indicator for manufacturing industries in China's provinces and cities,uses a three-stage Super-SBM DEA model based on the variable remuneration to measure China's provinces and cities (except Tibet) technology innovation efficiency,and to explore the influence of industry agglomeration on the technological innovation efficiency based on 2005-2014 Provincial Panel Data.Results show under the control of the openness and institution innovation,industry agglomeration has a positive influence on technological innovation efficiency;and with the promotion of industrial agglomeration,technological innovation efficiency decreases first,afterwords increases,then decreases,namely,the growth effect of industry agglomeration is in line with the ‘ inverted N-type’ hypothesis.
