Structural Diffusion Model and Urban Green Innovation Efficiency—A Hybrid Study Based on DEA-SBM, NCA, and fsQCA

This research is based on structural theory and innovation diffusion theory, exploring the theoretical foundations influencing factors of urban green to provide support for realization world’s sustainable development goals (SDGs). By using methods Data Envelopment Analysis with Slacks-Based Measure (DEA) non-expected model, Necessary Condition Research Methods (NCA), Fuzzy Set Qualitative Comparative (fsQCA) in combination, analyzes variables capability innovation. The study finds that level culture absorptive capacity are necessary conditions innovation, having a high influence. main paths comprehensive cultural path, an open inclusion participation integration outcome transformation drive path. In addition, discovered patterns influence go beyond institutional resource-based factors, subject action processes, models guided by absorption participation. results have important significance understanding driving promotion providing empirical evidence SDGs.
