当前中国的经济增长是以污染的大量排放为代价的。使用脱钩理论可以揭示经济增长与污染排放之间是否存在同步变化的关联,进而可为更好地实现污染排放的总量控制做好理论铺垫。文章以中国2004-2013年271个地级城市的面板数据为样本,先后考察了经济增长与环境污染脱钩的收敛性以及追赶脱钩状态。结果显示:(1)由于存在环境规制强度等因素上的异质性,区域脱钩状态呈现出"俱乐部收敛"特征,据此可以判定普通城市存在向标杆城市追赶的可能;(2)现阶段中国地级以上城市以"未追赶脱钩"类型的城市为主,大多数普通城市与标杆城市之间在经济增长与污染减排两方面的差距均不断扩大。由此引出的政策启示为:一是改变城市重经济轻环境的做法,二是差别化助推城市的绿色发展。
China's current economic growth comes at the expense of a lot of pollution. We could reveal the fact that whether there is a synchronous change link between economic growth and environmental pollution according to decoupling theory, thereby theoretically paving the way for total amount control of pollution emissions. Based on the panel data of 271 cities in China from 2004 to z013, this paper examines the convergence of the decou- piing between economic growth and environmental pollution and the status of chasing de- coupling. Results show that (1) regional development of decoupling shows the character- istic of "club convergence" due to the heterogeneity on the existence of environmental reg- ulation intensity and so on. The result suggests that it is possible for the ordinary cities to catch up the benchmark cities. (2) the no chasing decoupling cities are the mainstream in China, which shows that the gap between the ordinary cities and the benchmark cities in e- conomic growth and pollution reduction is expanding. The policy implications are as fol- lows= changing the way of attaching importance to economy while despising environment, and besides, the way of city green development needs differentiation.
