    摘要:

    在水污染排放税和排放权交易市场并行的现实政策情景下,模拟复合政策对地区重点企业的排放权配置结构、产量、利润和社会福利的影响,并探索实现社会福利和企业创新减排利润同时最优的政策区间。研究发现:相比于排放税,企业利润对排放权价格变化更为敏感;企业最优的从市场取得的排放权相对于超排量的比例与利润之间呈倒U形关系;在排放税税率与排放权单价的价差较小,且排放税率略低于排放权价格时,可实现经济与环境的双赢。为了使复合政策的效率最大化,建议减排政策中应避免排放税和排放权同低或同高的情形。

    Abstract:

    Under the compound policy scenario of water pollution emission tax and rights trading market, the complex impact of tax rights policies on the tax rights allocation structure, output, profit and social welfare was simulated. On this basis, the optimal policy interval for promoting enterprise to innovate was proposed. The findings are as follows. Compared with emission taxes, corporate profits are more sensitive to the price of emission rights. There is an inverted U-shaped relationship between the optimal ratio of emission rights obtained from the market to excess emissions and profits. When the price difference between the emission tax rate and the emission right unit price is small, and the emission tax rate is slightly lower than the emission right price, a win-win situation between the economy and the environment can be achieved. The research conclusion shows that in order to maximize the efficiency of the composite policy, the situation that the emission tax and the emission right are both low or high should be avoided in the emission reduction policy.
