粤港澳大湾区城市群技术进步的差异性——基于2007—2016年面板数据

Difference of Technological Progress between City Groups in Guangdong-Hong Kong-Macao Greater Bay Area:Based on Panel Data from 2007 to 2016

基于2007—2016年粤港澳大湾区城市群11个城市的投入产出数据,运用DEA模型、收敛理论和Deap2.1软件测算Malmquist生产率指数,并分解为技术效率和技术进步,分析区域发展的收敛性和差异性,回归结果发现:样本期内全要素生产率的年均增长率为-1.3%;技术效率的增长率为-1.6%,最高值为14.1%,最低值为-28.5%,变化幅度较大;年均技术进步增长率为0.3%,前期上升、后期下降,上升幅度大于下降幅度。纯技术效率呈下降趋势,规模效率呈上升趋势。总体来看,全要素生产率水平呈现下降趋势,各城市技术进步水平存在差异性,但差距逐渐缩小。

Based on the input and output data of 11 cities in the Guangdong-Hong Kong-Macao greater bay area from 2007 to 2016,the Malmquist productivity index is calculated using DEA model,convergence theory and Deap2.1 software,and is decomposed into technical efficiency and technological progress.The convergence and difference of regional development are analyzed.The results show that the average annual growth rate of total factor productivity in the greater bay area was-1.3%.The average growth rate of technical efficiency was-1.6%,though there was big variations with the highest of 14.1%and the lowest of-28.5%.The average annual growth rate of technological progress was 0.3%,which increased in the early stage but decreased in the later stage.The change of the pure technical efficiency showed a downward trend while scale efficiency upward trend.On the whole,the TFP level showed a downward trend,and the technological progress levels of various cities were different,but the gap was gradually narrowed.
