摘要:

为治理水污染,中国地方政府提出实施河长制。作为水污染的主要来源之一,农业面源污染的严重性日益突显。河长制是我国分权式环境监管体制下的一项制度改革,其能否有效地缓解非点源污染,对于实现绿色发展具有重要意义。基于2004-2015年308个县的面板数据,本文探究了河长制的农业面源污染防治效果。研究结果表明,实施河长制能够显著降低畜禽养殖对水质的负面影响。然而,河长制在处理因化肥施用而造成的水污染方面的效果不佳。此外,“河长”之间的合作只存在于同一个省内。地方政府应加大力度减少化肥源污染负荷,避免化肥源污染负荷进入地表水体。同时,中央政府应加强上下游省份河长之间的合作


Abstract:

As part of their efforts to control water pollution, local governments in China introduced the river chief system, whereby a named individual undertakes responsibility for protecting a specified waterway.  As one of the most prominent sources of water pollution, agricultural non-point-source (NPS) pollution is becoming increasingly serious.  Determining whether the river chief system, an institutional reform in China’s decentralized environmental regulation regime, is effective in alleviating NPS pollution is important for the realization of green development.  The effect of the river chief system on reducing agricultural NPS pollution is explored in this study using panel data from 308 Chinese counties during the period from 2004 to 2015.  The results reveal that the negative impact of manure output from animal breeding operations on surface water quality is reduced with the implementation of the river chief system.  However, the river chief system is ineffective in dealing with the water pollution caused by fertilizer use.  Furthermore, in the current system, cooperation among river chiefs only occurs within a province.  Local governments should increase their efforts in reducing fertilizer source loads and preventing fertilizer loads from entering surface waters.  In addition, the central government should improve cooperation among the river chiefs in upstream and downstream provinces.
