Because of city’s huge role in promoting the developing of national economy madeurbanization become the only way of national development. The21st century is thecentury of city of human society. As a developing country, China’s urbanization still hasa long way to go. In the context of economic globalization, the city is an important nodeof the national economy and the world economy docking, in order to occupy a certainposition in the international economic division; we must to develop our own city in theworld economy network. Developing and expansion the city is every developingcountry’s only choice to seize the opportunities brought by economic globalization, andaccelerated into the development of the world economy.After introduces the research background and analysis the past literature studies,the nature and content of cities and urbanization were discussed in this paper, and findthat urbanization is not a simple scale, or the rural population move into cities. HealthyUrbanization should be able to ensure that the elements in the city gathered to areasonable form, only that can effectively promote the emergence while reducing thecosts of emerge, but also promote the development of surrounding countryside andsmall towns by diffusion and radiation functions, improve the city’s own strengths andarea influence. Then through analysis of the relationship between the urbanization andeconomic, Preliminary proves urbanization is the only way for the country’sdevelopment, and briefly introduces the different divisions of the urbanizationdevelopment stage theory.The paper’s core theory is emergence. The article draws agglomeration economiesand complex adaptive systems theory analysis the concept of emergence and theconditions for emergence. And think that emerged is more like a manifestation of theresidual value of a city. And make a further analysis in emerged in the urbanizationprocess, including the emergence of talent, wisdom, science, technology and so on.Fundamentally improves that city is the only way for the development of a country,thereafter also provides a brief analysis of the emergence also bring negative effects,that is, the emergence costs, so each city must see the emergence’s benefits, but also payattention to the costs.The author hope that reflect the emergence of cost and benefit’s balance in the sizeof the cities, so after the study of emergence theory, analysis the size of the city and analyses the past theory, find the common problem of previous scholars’ study ofreasonable size of cities. The author believes that each city has a reasonable size in aparticular period; all theoretical studies are based on certain assumptions and conditions,so the study of reasonable size of cities should be mindful of the limitations of thetheoretical research. This article particular mentions this when study reasonable size ofcities based on the emergence theory. After this, with the available data, see the divisionof the different spheres of Chengdu as the different stages of urban scale’s development,tests the emerged theory. In the end of the article, summarizes the conclusion of thisarticle, and puts forward few brief comments to contribute to the process of theurbanization in China..
