摘要:应用财富效用函数研究了不完全竞争市场下排污权交易的价格形成模型。首先,借助排污权交易中出售方与购入方所获利润的财富效用函数,构造排污权交易定价的协商模型,推导出排污权交易价格的边际效用零和方程。再而,由于排污权市场的交易价格受交易价格偏好、交易成本、市场势力、预期排污权价格等因素的影响,借助案例计算分析了交易价格偏好、交易成本、市场势力等参数的不对称性对均衡价格的影响,并佐以图表形式说明。

Abstract:The pricing model of emission rights transaction under imperfect competitive market is built by using the wealth utility function in this paper. First, by means of the wealth utility function of the profit obtained from the sale and the purchaser, constructing the bargaining pricing model of emission rights, the marginal utility zero sum equation of the price of the emission trading is deduced for solving the emission trading price. As the transaction price of the market is affected by the transaction price preference, transaction cost, market power, expected emission price and other factors, then the asymmetry of parameters affect equilibrium price is analyzed by case calculation. And it is illustrated in graphical form.
Key words:pricing of emission rights; wealth utility function; equilibrium price; initial emission permits
中国经济高速粗放增长伴生的环境污染问题是国家生态文明建设的难点之一,其中水环境问题较为突出,表现为水质较差状况没有从根本上改善,全国地表水污染依然相当严重;污染物排放总量大,超出水环境纳污负荷,对水生生态系统构成威胁;水污染问题加剧了水质型缺水,既影响居民的正常生产生活,也不利于中国社会、经济、环境的可持续发展。
作为目前全世界各国处理环境污染问题的重要对策[1],排污权交易成为国内广泛研究探讨的对象。一方面,国内学者在理论引进、机制设计、初始分配、试点经验共享等方面做了大量工作。另一方面,随着国内排污权理论的成熟,试点经验的丰富以及机制设计的多角度多元化发展,排污权交易的定价问题逐渐浮出水面。……
