Investigating the Spatial Spillover Effect of Transportation Infrastructure on Green Total Factor Productivity

Green development and the high-quality economic growth model have replaced extensive in an effort to reduce large amounts of energy consumption pollution emissions. total factor productivity has become important indicator more accurately measure quality growth. Transportation infrastructure is a fundamental component that may effectively integrate regional resources, increase cooperation, encourage sensible use key increasing productivity. At present, transportation should focus on speed construction level, expand radiation range system, improve service level facilities, promote spatial coordination between facilities resources environment each province. Therefore, it great significance study effect transport green order understand role its impact In this study, slacks-based (SBM) global Malmquist–Luenberger (GML) index were used calculate 30 provinces China, while was investigated based Durbin model. national road density, railway show positive spillover effects. The inhibits productivity, there obvious heterogeneity eastern, central, western regions. process construction, we not only pay attention scale expansion but also pursue service. same time, measures such as flow talent introduction foreign capital within region be constantly coordinated improvement achieve win–win situation environmental protection.
