Demand for energy is growing with each passing day by the rapid development of economy in Jiangsu Province. Energy shortage is one of the restricting factors on the further development of economy. Meanwhile, environment pressure with energy consumption is increasing day by day. So, how to realize the coordinative development among energy and economy has been an important problem which should be solved as soon as possible. Based on the energy and economy data from 1995 to 2009, this article is to set up the development evaluation index system and the energy-economy coordinative degree model, which aims to analyze the coordinative development level quantitatively among energy and economy. The results show that the coordinative development level among energy and economy has experienced the following changes: 1) from 1995 to 1997, the coordinative degree presented slow rising trend as a result of the low development level both in energy and economy; 2) the development speed of economy was faster than that of energy, which caused the coordinative degree declining briefly in 1998; 3) the development level from 1999 to 2004 improved at the same speed. Due to most high-energy-consumption enterprises being closed successively and new technology and new equipments being adopted, energy utilization efficiency increased greatly which presented short "harmonious" state between energy and economy; and 4) the coordinative degree was declining slightly for the excessive consumption of energy resources in 2005. The government intensified efforts to transform the mode of economic development and to adjust the industrial structure. In this case, the coordinative degree rised again from 2006 to 2009, which meant the optimization period had been coming. However, problems such as energy consumption per unit of GDP being on the high side still exist. The contradiction between energy and economy is still outstanding. During the period of the 12th Five-Year Plan, Jiangsu will keep the coordinative development level in primary state and achieve the sustainable development among energy and economy by adjusting industrial structure, optimizing energy structure, improving energy utilization efficiency and strengthening national energy saving consciousness further. At the same time, Jiangsu will put solving the environmental problem on the more prominent place. By the joint efforts, Jiangsu will become an economy-healthy, resources-saving, and environment-friendly society.
