Comparative Analysis Chinese Green Buildings' of Input–Output Effect Based on Data Envelope Analysis.

In order to measure implementation management efficiency of Chinese green buildings, the input–output index system of Chinese green buildings was constructed base on provincial-level panel data during 2017–2021.The basic model Data Envelopment Analysis (DEA) and DEA-Malmquist index method were adopted to measure and analyze the development law and time–region evolution tendency of implementation efficiency of Chinese green buildings from the static and dynamic perspectives, contributing to clarifying critical factors of restricting green building development, respectively. It was found that the comprehensive implementation management efficiency of Chinese green buildings was lower, but the development tendency was good. There was a remarkable regional and provincial difference, showing the development pattern of "east > middle > west" as a whole. Pure technical efficiency did not have a big gap, but most areas kept an invalid scale state, resulting in fluctuations of regional efficiency in varying degrees. The average annual increase of Total Factor Productivity (TFP) was 14.80%, indicating that TFP was developed well. Technical progress was considered as a decisive factor to restrain increase or decrease of TFP. As a result, to improve implementation efficiency of Chinese green buildings, it is necessary to focus on destroying the regional limitations, optimizing the input scale moderately, and paying attention to technical progress and innovation management.
