配额免费分配法下市场结构对碳交易市场运行效率的影响
Study on the effect of market structure on carbon emission trading market performance under free carbon emission allowances
摘要
Abstract
Carbon trading mechanism is an effective environmental policy when both product market and carbon emission trading (CET) market are under the perfectly competitive conditions.However, neither of these two markets tend to achieve perfect competition in current realistic situation.Using complex adaptive system and simulation method, a model of CET market is built based on the SWARM to emulate the real market, which is aimed to study the relationships between CET market and the structure of product and CET market from a comprehensive point of view.Meanwhile, in order to weaken the negative effects of product market monopoly on the efficiency of CET market, two methods are used to explore the valid carbon trading mechanism in imperfect competition market condition.One is increasing the gaps between carbon quota supply and demand, and the other is increasing the number of small and medium sized Companies involved.It is found that: ①Monopoly in product market leads to the lack of liquidity and clustering of volatility in CET market.②Monopoly in CET market would bring less volume and turnover, i.e.lower liquidity, when the product market conditions remains unchanged.③Market structures have no significant influence on the price of CET market.④The structure of product market will affect the effectiveness of CET market, the earnings fluctuation of carbon market is in accord with random walk process in perfectly competitive market, while things are different in monopoly market.⑤The market liquidity will improve notably along with the increasing gap between quota supply and demand, which shows the volume and turnover increase correspondingly.In the monopolistic product market, the limited quota supply may improve the liquidity in CET market and promote the volume of transactions.⑥It has no significant effect on the liquidity of carbon market to encourage the small business involved.But it's helpful to reduce the control power of the monopolies and improve the market efficiency.The results of this study provide beneficial reference for the establishment of united national carbon trading market in China.关键词
