Assessing green innovation efficiency and spatial characteristics of China’s high tech industry based on the three stage undesirable SBM model

We propose a comprehensive research framework for evaluating the GIE of China’s high-tech industry and analyzing their spatial characteristics (Fig. 1). Beginning with defining GIE in the high-tech industry, this study selects input-output indicators and technological environmental variables, employing the three-stage undesirable SBM model for calculation. The Theil index is used to analyze the spatial differentiation … Read more
