Abstract:
This paper comprehensively interprets the targets of RCS (River Chief System) from four aspects, which are water pollution reduction, water environment improvement, water resources management, and water function improvement. On this basis, it builds the effectiveness evaluation system of RCS in Jiangsu. According to the spatial panel data of cities and districts in Jiangsu Province from 2006 to 2015, this paper systematically analyzes the present situation and regional differences of the implementation of RCS in Jiangsu Province. It is found that during the first decade since the RCS was implemented, its effectiveness has experienced a rapid growth period before 2010, a fluctuating growth period from 2011- 2012, and a rapid development period from 2013 to the present. At the spatial level, the effectiveness of the RCS tends to diminish from southern Jiangsu to middle Jiangsu and to northern Jiangsu. In the recent three years, the growth of effectiveness of RCS in Jiangsu Province is fast in the north and slow in the south, and the spatial difference has gradually narrowed. Finally, the paper puts fo rward the following suggestions: to improve the evaluation system as well as reward and punishment system of the RCS, to strengthen the research and promotion of the technologies of water ecological civilization construction, to promote the RCS in urban and rural areas simultaneo usly, and to make full use of civil forces and capital for water control.
