How does technological progress impact transportation green total factor productivity: A spatial econometric perspective

The improvement of transportation green total factor productivity (GTFP) is crucial to the highquality development of China's economy under the new normal. Through dynamic and cross-regional comparison of transportation TFP and transportation GTFP, the driving force of transportation GTFP growth was analyzed. An augmented production function model and the geographically weighted regression (GWR) model were combined to analyze the spatial impact of technological progress on transportation GTFP The results are as follows: the effect of R&D investment on transportation GTFP first decreases and then increases. The impact factor of interprovincial technology spillover (DS) on transportation GTFP was always negative during the study period. The influence of foreign direct investment on transportation GTFP depends on the pollution havenand pollution haloeffects. We highlighted the need for regional coordinated development and encouragement of green technology spillover. We should also promote the GTFP growth with regional differentiation.

Automated summary

The study found that the impact of R&D investment on transportation GTFP first decreases and then increases, while the impact of interprovincial technology spillover on transportation GTFP is always negative. The influence of foreign direct investment on transportation GTFP depends on pollution havens and pollution halo effects. Therefore, promoting regional coordinated development and green technology spillover is essential for GTFP growth.
