Does Rapid Urbanization Improve Green Water-Use Efficiency? Based on the Investigation of Guangdong Province, China

The green water-use efficiency considers the undesired output of water pollution discharge as well desirable output, pursuing unification economic and ecological benefit. In recent years, China has been undergoing a process rapid urbanization dramatic change in utilization pattern, while is becoming more obvious. Taking Guangdong Province an example, largest economy pilot area, exploring impact different aspects on great significance for promoting new-type development. This study adopts super slack-based model (SE-SBM) considering undesirable to measure each city Province. On this basis, mixed panel, random fixed panel models are used explore relationship between industrial urbanization, population land social urban-rural integration efficiency. results reveal that Guangdong’s follows low upward trend. Pearl River Delta improved rapidly, other regions maintained at level, so regional disparities also widening. Industrial have significant positive effect efficiency, negative effect. not significant. construction should be accelerated, transformation upgrading industries guided, agricultural migrants promoted. It necessary rationally plan utilize urban resources comprehensively improve functions livability.
