Spatiotemporal Differentiation and Influencing Factors of Green Technology Innovation Efficiency in the Construction Industry: A Case Study of Chengdu–Chongqing Urban Agglomeration

In order to support the green and low-carbon transformation of China’s construction industry accomplish dual carbon objective, it is vital accelerate technology innovation. Therefore, this paper takes Chengdu–Chongqing urban agglomeration China as study area, using super-efficiency slacks-based measure (SBM)model gravity model assess efficiency innovation in industry, utilizing geographical detectors investigate drivers further. Additionally, we consider each influencing factor’s level impact on sector both under single factor double scenarios. The findings indicate that there a considerable difference metropolitan agglomeration’s trend upward. addition, research area exhibited spatially heterogeneous characteristics terms spatial spillover effect was significantly limited by distance. Further revealed environmental legislation, economic development, public concern, urbanization level, foreign direct investment were primary driving factors sector, industrial size potential factor. temporal differentiation also more affected interaction between dominating prospective than either acting alone. research’s are useful advancing offering theoretical decision-making reference.
