摘要: 日趋臻显的行业细分趋势和显著的外向型经济发展特点等在很大程度上决定了我国区域排污权交易系统内不存在显著的产品竞争。鉴于此,在产品异质条件下,通过考虑产成品市场与排污权交易市场之间的关联影响,首先从理论层面分析了社会最优的排污权配置状态;进而,构建了主导企业与从属企业之间的主从博弈模型,通过分析特定排污权市场价格下从属企业的最优行为特征,深入剖析了主导企业的策略性行为及其对系统均衡的影响。结果表明:市场支配力对系统均衡的影响具有多样性与复杂性;特别是,为了获取更大的额外收益,主导企业存在作为卖家时选择"溢价"与作为买家时"抑价"两种排污权价格操纵形式,并不可避免地导致系统均衡与社会最优配置状态的偏离,而从属企业却会蒙受巨大损失;其中,初始排污权禀赋是影响主导企业最优决策的重要因素。最后,通过量化分析对结论进行了验证,并细致展现了主导企业产污系数和治污成本等变动对系统均衡的影响。

Abstract: The market power has become a key problem to limit the extent to which emissions trading systems can fulfill their theoretical promises. Prior research has concentrated on market manipulation by firms seeking to minimize the compliance costs, and exclusionary manipulation within a particular sector under emissions trading system. However, the increasingly significant trends of industry segment and the characteristic of export-oriented economic development largely cause the absence of significant products competition in China's regional emissions trading system. In view of such conditions, the issue of market power in emission trading systems under heterogeneous product condition is mainly explored by taking the interaction between emissions trading system and product markets into account. As the research base, the socially optimal allocation condition is analyzed using a non-linear programming model firstly. Then, a Stackelberg game model between the dominant firm and the fringe firm is constructed in order to examine the strategic behavior of dominant firm and its impact on the system equilibrium by analyzing the optimal decision of fringe firm under specific permit price. The results show that market power has a diverse and complex influence on the system equilibrium. Especially, in order to obtain the windfall profit, the dominant firm would choose two price manipulation strategies:"premium-pricing" strategy while it acts as a permit seller and "under-pricing" strategy while it acts as a buyer. These strategies inevitably cause the deviation of system equilibrium from socially optimal state and the large profit loss of the fringe firm. Moreover, the initial endowment of emission permits is the crucial factor affecting the decision making of the dominant firm. Finally, a quantitative analysis is used to verify conclusions of the analysis, and demonstrates the impact of changes of pollutant producing coefficients of the dominant firm, abatement cost and so forth on the system equilibrium particularly.

Key words: emissions trading, market power, price manipulation, product heterogeneity, system equilibrium
