A series of strategies for solving the problems was put forward, including accurate orientation of the natural gas industry, strengthening the construction of gas transmission and distribution networks, comprehensive exploitation policies for ＂integration of up-and-downstream＂, government-supported gas-preferential policies, construction of the gas market frameworks and devoting strong effort to the new market development.展开更多
