Abstract:

This paper, from both flow flux and flow direction, evaluated and discussed the balance status of coal resource flow and problems in the Chongqing City of China. The paper next made a prediction of importing coal for the next 5 years, and based on the projected results, it put forward some policy suggestions. The study revealed as follows.
(1) Coal production and consumption in the Chongqing City were unbalanced, and its selfsupport ratio decreased year by year. Therefore, it required a lot of coal from other provinces to make up for its shortage. The coal liquidity ratio in Chongqing City was rising, and the coal flux flowing into Chongqing City was also growing. All those indicated that external coal dependence for Chongqing City was continuing to strengthen.
(2) Due to rapid economic development, coal production and consumption in the Chongqing City became unbalanced. So, economic development was the determinant for the continued strengthening of coal resources flow in Chongqing City. Coal resources potential difference was the main factor to determine coal resources in surrounding regions flowing into the Chongqing City. And based on above factors, which concrete coal source Chongqing City chose would depend on the cost of distance and transportation.
(3) In the coalrich regions around the Chongqing City, Guizhou and Henan played minor roles in making up for the coal shortage, and Shanxi，Ningxia and Xinjiang should become important coal supply sources. Therefore, speeding up the planning and construction of railway from Shanxi and Xinjiang to Sichuan and Chongqing should be the focus of national coal railway transportation planning.
(4) According to the projected results of importing coal from other provinces in the next 5 years, this paper presented that Chongqing City could improve coal transport capacity of highway and waterway in the short term to solve the energy bottleneck. In addition, Chongqing should play Yangtzes role as Golden waterway as well as its harbor advantage, and strengthen the construction of coal reserve base and coal transfer terminal, which were effective initiatives to guarantee the stable coal supply and energy security in the future in Chongqing City
