摘要
This study presents the empirical analysis of production efficiency of non-ferrous metal industry both from static and dynamic aspects by using DEA models and the Malmquist index based on 29 provinces' panel data from 2006 to 2010 in China. The static analysis results show that the production efficiency of non-ferrous metal industry is generally low and greatly influenced by local economic development and that the inefficiency of the whole non-ferrous metal industry is mainly caused by the inefficiency of pure technical efficiency. The regional development of the non-ferrous metal industry is unbalanced. Based on the dynamic analysis of MI, the gap in production efficiency of the non-ferrous metal industry among provinces has gradually widened. Productivity takes on a rising trend in general impacted mainly by the force of advancing technology as the mean of MI is greater than one. The fluctuation of technological progress is negatively correlated to that of technical efficiency, and this interactive fluctuation creates a rising trend of productivity. Also presents some discussions for instructing the healthy and circular economic development of the non-ferrous metal industry.
