产业融合对全要素生产率影响的空间效应研究——基于先进制造业与现代服务业融合的视角

Spatial Effect of Industry Convergence on Total Factor Productivity:From the Perspective of the Convergence of Advanced Manufacturing Industry and Modern Service Industry

为了评估产业融合对全要素生产率的影响,在构建先进制造业与现代服务业融合指标体系的基础上,测算产业融合水平,运用随机前沿法计算全要素生产率,通过面板半参数空间滞后模型研究产业融合水平对全要素生产率的影响。研究发现,中国产业融合水平整体呈上升趋势,然而区域间的发展差距逐渐扩大,产业融合发展不均衡现象依然存在;全要素生产率整体呈先下降后上升的发展态势。分解来看,规模效率贡献稳定上升,技术进步率的贡献相对较弱;产业融合水平对全要素生产率的影响存在显著的空间效应,某地区的全要素生产率受到周边地区的影响,并且这种影响存在非线性效应,产业融合对全要素生产率当融合水平低于0.360时呈现抑制效应,当融合水平等于或高于0.360时呈现促进效应,随着经济的发展,呈现促进效应的地区将逐渐增加。

To evaluate the impact of industry convergence on total factor productivity,the paper constructs an index system for the convergence of advanced manufacturing industry and modern service industry,and measures the level of industry convergence.In addition,it calculates total factor productivity with stochastic frontier method,and studies the impact of the level of industry convergence on total factor productivity with semi-parametric spatial lag model.The results show that the level of industry convergence in China is on the rise as a whole,but the development gap between regions is gradually widening,and the development of industry convergence is still unbalanced.In addition,total factor productivity first declines and then increases.Individually,the scale efficiency is steadily rising,but the effect of technological progress is relatively weak.There is a significant spatial effect of the level of industry convergence on total factor productivity.The total factor productivity of a region is affected by its surrounding areas,which carries the characteristic of nonlinearity.When the level of industry convergence is lower than 0.360,it has a restraining effect on the total factor productivity.When the level of industry convergence is higher than 0.360,it has a facilitating effect and the number of areas falling into the facilitating effect zone is gradually increasing.
