In this study, remotely sensed images with approximately 30 m spatial resolution were used to quantitatively assess the spatial and temporal patterns of urban expansion of 60 Chinese cities(1973–2013). Urban-expansion-process curves of the cities studied were drawn using annual expansion area as an indicator. Curve similarity analysis generated four basic process modes of urban expansion in China. These included cities that: 1) peaked around 2004 and then decelerated; 2) peaked around 2010 and then decelerated; 3) showed sustained acceleration, and 4) showed continued deceleration. Four basic process modes represented cities under different levels of development stage. Geographic location was found to be the most related characteristic to urban expansion process. Regional development policies at the national level in each region also showed highly temporal consistency with fluctuation characteristics of urban expansion process. Urban characteristic such as population size and administrative level were not found to be significantly related to urban expansion-process modes. Understanding the basic process-mode categories well is extremely important for future regional-balance planning and development of macroeconomic policies.展开更多

Practice shows that the impact of fiscal policy on China' s fixed asset investment is direct and obvious, yet sometimes too drastic. In the future, fiscal policy should be used in alignment with other economic policies with appropriate intensity and timing so that it will help stabilize the growth of fixed asset investment.展开更多

In other words, economic imbalance is regarded as the cause of the problem and fiscal expansion as the result. However, this paper posits that China's expansive fiscal policies may also be a major cause of its economic imbalance, and that fiscal expansion and economic imbalance create cumulative causation. Specifically, China's tax system, characterized by a regressive commodity tax, intensifies constraints on domestic consumption while distributing a large proportion of national income to government and enterprises; supply-demand imbalance prompts the government to expand fiscal expenditures and increase taxes, which further exacerbates this imbalance. Thus, even as the country faces a macroeconomic imbalance, the strong measures it adopts in response may stimulate economic growth in the short term, but in the long term, they may do exactly the opposite and create the next economic crisis.展开更多
