An Assessment of the Green Development Efficiency of Industrial Parks in China : Based on Non-Desired Output and Non-Radial DEA Model

Greening the industrial parks is one of China's attempts to explore sustainable development for the industrial sector. In this paper, a non-desired output and non-radial DEA model was firstly proposed for measuring a number of industrial parks’ green development performance. We use the panel data of 171 certified green industrial l paparksy China’s central government to evaluate the green development efficiency. The results show that the green development efficiency of the industrial parks exhibits significant spatial and temporal heterogeneity. The overall scale efficiency outperforms technical efficiency. We further decompose the green development efficiency and analyze the input redundancy and output insufficiency which shows that the non-desired output for solid waste and wastewater is relatively higher than the bad air in these industrial parks. We explore the green development measures which can be replicated and promoted, and contribute to the green development of industrial parks in China and other developing countries
