Spatial Disequilibrium and Dynamic Evolution of Eco-Efficiency in China’s Tea Industry

Eco-efficiency is a significant target for evaluating the agricultural ecosystem and measuring sustainable development through quantitative analysis. It also an essential part of constructing ecological tea garden, which offers directional function in realizing green industry. After eco-efficiency China’s industry using super-efficiency SBM model, this paper analyzes spatial disequilibrium dynamic evolution trend method Dagum Gini Coefficient Kernel Density Estimation. The results show that level was improved overall, significantly reduced. differences within region decreased as follows: regions Southwest China, South south Yangtze River, north River; overall difference mainly comes from contribution interregional regions, second intraregional super-variable density. has been both nationally top four regions; between areas largely alleviated, but there still room to optimize input–output structure promote eco-efficiency.
