美国煤电合约特点及对我国的启示

Coal-Power Plant Contract in America and Its Enlightenment to China

从交易成本经济学的角度来看,煤炭产业和电力产业适合选择长期合约的合作方式。以美国煤电合约为研究对象,分析在20世纪80年代后美国煤电合约期限缩短(即由原来长期合约为主变为5年期以下的合约占主导)的原因。从以下三个方面对此现象做出解释:能源市场波动削弱了煤炭企业的谈判势力;电力市场放松管制增强了电力企业的谈判势力;其他政策法规产生约束作用。最后结合我国煤电合约现状,借鉴美国构建稳定煤电关系的经验,为缓和我国煤电矛盾提出如下建议:加快实现竞价上网,放松发电企业管制;完善合约条款设置;转变政府参与角色。
