Research on the Industry Environmental Total Factor Productivity in Jiangsu Province Based on the Non-radial DDF

Abstract

This paper uses the non-radial DDF to measure the industry environmental total factor productivity in Jiangsu province of its 13 cities during 2005-2015 with SO2 emissions as the undesirable output, and discomposes the total factor productivity into the pure technical efficiency, the scale efficiency change and the technical change. The research shows that the overall trend of the industry environmental total factor productivity is increasing in Jiangsu province during 2005-2015, the technical change is a main reason pushing up growth rates of economy, and the pure technical efficiency change is the intrinsic motivation.
