Abstract:
Water use structure, water pollution discharge structure, and industrial structure interact with each other, therefore knowledge of the evolution characteristics of current industrial water use and pollution discharge structure plays an important role in optimizing the industrial structure. In this paper, the comparable price input-output tables considering water use and pollution discharge were developed to analyze the evolution characteristics of water use and pollution discharge structure of Jiangsu Province from 1997 to 2007 from four aspects—water use, water pollution, water use characteristics (water use efficiency and profit), and water pollution characteristics (pollution discharge efficiency and profit) with the application of information entropy theory. The results showed that (1) the water use structure tends to develop orderly and its equilibrium degree has weakened; (2) the development of water pollution discharge structure is out of order and its equilibrium degree has increased; (3) the water use characteristics structure tends to develop orderly, and its equilibrium degree has weakened; and (4) the water pollution efficiency structure is in opposite development compared with the water efficiency structure.
