With China’s rapid economic development, the economic transformation and emission reduction based on energy conservation are the two key problems of Chinese economic development. In this article, we made quantitative analysis to the energy conservation and emission reduction ofJiangsuindustrial restructuring and industrial technology progress by using the model of input-output methods with the data ofJiangsuinput-output table in 2007. The result showed that if energy consumption caused by per unit output in the industry higher than average level of all the industries, we can decrease its proportion of all the industries. However, if the industry is the pillar industry to the national economic development, we cannot largely decrease its proportion. During this background, improving the technical level of theIndustry to reduce the energy consumption is a better choice. This article analyzed the contribution to energy conservation and emission reduction by industrial restructuring and industrial technology progress from the quantitative aspect.
