加速城市化已被视为经济发展的重要工具，并减少了包括中国在内的一些发展中国家的区域差异（Bloom，2008年）。近几十年来，中国城市的城市化与经济增长之间的因果关系，使用建筑领域作为一个景观城市化指标，我们的分析表明，在人口规模和建筑面积方面，更大城市建筑区域的扩张和人均GDP在城市和省级水平上，以及省级的双向因果关系，揭示了景观城市化与中国城市经济增长之间的积极反馈，如果我们的成果在中国的范围内，以及在中国的范围内，在中国的范围内，这两者都在范围内生效。不仅是城市经济增长的后果，而且结果的驱动因素还表明，在目前的经济增长模式下，中国可能很难在不牺牲经济增长的情况下控制城市的扩张，而在其制止农业土地上损失的政策可能会受到其政策促进通过城市化促进经济增长的挑战。
Accelerating urbanization has been viewed as an important instrument for economic development and reducing regional income disparity in some developing countries, including China. Recent studies (Bloom et al. 2008) indicate that demographic urbanization level has no causal effect on economic growth. However, due to the varying and changing definition of urban population, the use of demographic indicators as a sole representing indicator for urbanization might be misleading. Here, we re-examine the causal relationship between urbanization and economic growth in Chinese cities and provinces in recent decades, using built-up areas as a landscape urbanization indicator. Our analysis shows that (1) larger cities, both in terms of population size and built-up area, and richer cities tend to gain more income, have larger built-up area expansion, and attract more population, than poorer cities or smaller cities; and (2) that there is a long-term bidirectional causality between urban built-up area expansion and GDP per capita at both city and provincial level, and a short-term bidirectional causality at provincial level, revealing a positive feedback between landscape urbanization and urban and regional economic growth in China. Our results suggest that urbanization, if measured by a landscape indicator, does have causal effect on economic growth in China, both within the city and with spillover effect to the region, and that urban land expansion is not only the consequences of economic growth in cities, but also drivers of such growth. The results also suggest that under its current economic growth model, it might be difficult for China to control urban expansion without sacrificing economic growth, and China’s policy to stop the loss of agricultural land, for food security, might be challenged by its policy to promote economic growth through urbanization.
