Appraising Model of Utilizing Efficiency of Resources and Environ- ment for Industry and empirical study in Guangxi and Guangdong
2011, 26 (1):
The industrial is the most important economic activity of human and has a significant influence on the resources and environment. The relationship among the resources input, economic benefit and environmental pollution determines the utilizing efficiency of resources, environment for industrial economy. But the existing literatures ignore the construction of integrated appraising model on this topic. Based on the review of progress in research, we design the appraising model of utilizing efficiency of resources, environment for industrial economy, including TOPSIS model and SBM of DEA model. The TOPSIS model can merge the several indexes into a synthesis index of resources input, economic benefit and environmental pollution respectively, and provide an integrated discussion. The SBM model of DEA considers the environmental pollution as an un-expected output in the calculating process which is different from the other existing models, and appraises the utilizing efficiency of industrial economy of each specimen region. This model improves the appraising method in this field. Then taking 35 cities in Guangdong and Guangxi provinces as the case region, we describe the spatial pattern of resources input, industrial benefit and environmental pollution respectively, and analyze the efficiency level of industrial economy of each region, and discuss the corresponding relationship between utilizing efficiency of industrial economy and input-output of industry. The result shows that there are two kinds of regions with the efficiency and inefficiency of industrial economy respectively. Twenty cities in the Pearl River Delta, north Guangdong and the coastal regions in east Guangdong and southwest Guangdong, and west Guangxi and southwest Guangxi have the efficiency of utilization of resources and environment for their industrial economy. But 15 cities in east Guangxi and north Guangxi and northwest Guangdong have the inefficiency of industrial economy and those cities are distributed uninterrupted. Moreover, we identify the causation of un-efficiency of industrial economy of each city in Guangdong and Guangxi. The discussion of SBM model demonstrates that the inefficiency of industrial economy largely results from the resources input and un-expected output, including over discharge of the pollutants and the over consumption of land resources, water resources and energy such as the coal, oil and electric power. Then the cities in Guangdong and Guangxi have the enormous potential on the reduction of industrial waste water, waste gas, and on the decrease of water resources, land resources, labor, capital and energy to improve the efficiency of industrial economy. Especially the technical renovation of industrial enterprises, such as the renewal of equipment and the equipment of pollutant disposal, and the improvement of environment access threshold of industrial enterprises, become the practical approaches to enhance the utilizing efficiency of resources and environment input for the industrial economy.
