The new urbanization is a historical reflection on the traditional urbanization，the targets of new urbanization are constrained to increasingly exhausted energy and ecological destruction which lead to unsustainable economy, so actively developing new energy sources plays a important role in new urbanization． For that reason, in the new energy sources context, this paper employs evolutionary game theory to build evolutionary game model of investment and financing mechanism of new energy sources, pays a greatly attention to analyzing the factors affecting strategy selection of each game subject in order to explore evolutionary stable strategy． The dynamic evolutionary process in different initial state is examined with the aid of numerical analysis． In addition, this paper puts forward a series of policy suggestions in new energy sources development．
