The number of large and very large cities is the greatest in China: there aretwenty-eight cities of 50,000 to one million population, and thirty of over one million, thelatter being regarded as meg-citics. There are nine of over two million population,amongst which Beijing has 10.4 million(1990)and Shanghai has 12.8 million(1990).Planning and research of the mega-cities tend to be locally specific and what is lackingseems to be an overview of the common and general issues in their development.展开更多

Thus the key of the supply-side structural reform lies in breaking through the long-term path dependence and facilitating the transformation and innovation of socio-economic and urban development. This paper takes Shenzhen as the benchmark of the comparative study, and Guangzhou and Tianjin as the comparative object to analyze the contributions of the demand-side 'troika' – investment, consumption, and export, to economic growth from 1986 to 2015. Then, it introduces multiple growth elements on the supply-side to analyze the significant contribution elements in urban economic growth and their contribution degrees. Meanwhile, in combination with the economic development background and the policy guidance since the reform and opening up, the paper analyzes the characteristics of the development paths and their trends of the three cities. In the end, based on the comparative study, it carries out a discussion on the development path for mega-cities and their urban planning strategies at the new era from three perspectives.展开更多

The Beijing-Tianjin-Hebei area, Yangtze River Delta area and Pearl River Delta area are China's three largest and most mature mega-city regions, the status of which represents the general level of the urban and regional development in China. Based on entire-array-polygon method, this paper makes a comprehensive evolution assessment of the three mega-city regions in terms of urban population index, urban economy index, urban life index, urban culture index and urban primacy index. In terms of general developing level, the three mega-city regions have progressed to optimize the structure. With their respective advantages and disadvantages, the three mega-city regions initially realize a "diversified" regional layout. The diference and gap among the three mega-city regions are obviously decreasing, which contributes to the regional balance of China metropolitan development. The rankings of the three mega-city regions will be in a continuous adjustment. The Beijing-Tianjin-Hebei area is possible to catch up and take the lead.展开更多
