New Economic Geography has gained great fame, despite of its short history of more than 20 years. Its core concept is to emphasize the spatial non-continuity and non-monotonic of economic growth, subsequently to explain the regional economic development differences. It is the first approach that New Economic Geography has illustrated the endogenous location choice mechanism of economic activities in a general equilibrium setting. The spatial distribution of economic activities is not only related to technology spillover and environmental pollution, but also related to trade liberalization. Technology spillover effects are associated with space distance. As the increase of technology spillover effects between regions, the industrial dispersion force is enhanced and the economic spatial structure is changed from the asymmetric structure to symmetric structure. Environmental pollution inevitably affects the production cost of capital production department. The increment of environmental pollution spreading effect between regions will strengthen the industrial agglomeration and promote the change of structure from symmetric to asymmetric structure. The change of trade freeness can result in all kinds of stable state of industrial spatial structure that includes full agglomeration and symmetric spreading as well as partial agglomeration. Although the unbalanced development of the spatial concentration of economic activities is an insurmountable stage of the national economic development in the early, but the resulting regional economic differences will eventually disappear with the deepening of economic integration.
