As the problems of "valuing compliance over trading" and quota over-allocation seriously affect the effectiveness of China's national carbon emission trading (CET) market, the quota auction mechanism will be introduced timely to solve these problems. Since implementing the quota auction means reduced free quotas, regulated enterprises are more motivated to pursue low-carbon technology innovation (L-CTI). On these grounds, by establishing a system dynamics model of the national CET market and designing seven scenarios for simulation analysis, this paper investigates the impact of quota auction and L-CTI on the emission reduction effectiveness and cost effectiveness of the national CET market. The results indicate that for the national CET market, introducing quota auction is conducive to decreasing the CET price and improving its liquidity and emission reduction effectiveness, which is one of the quota allocation mechanisms to improve the CET market effectiveness at present. However, the quota auction will increase the abatement cost and reduce the cost effectiveness. Therefore, to improve the institutional performance of China's CET system, it is necessary to conduct L-CTI to alleviate the increasing abatement cost caused by quota auction, and thus improve the emission reduction effectiveness and cost effectiveness of the national CET market.
由于“重履约、轻交易”和配额过度分配问题严重影响了中国全国碳排放交易（CET）市场的有效性，因此将及时引入配额拍卖机制来解决这些问题。由于实施配额拍卖意味着减少免费配额，受监管的企业更有动力追求低碳技术创新（L-CTI）。基于此，通过建立国家 CET 市场的系统动力学模型，并设计了七种情景进行模拟分析，本文探讨了配额拍卖和 L-CTI 对国家 CET 市场减排效果和成本效益的影响。结果表明，对于国家 CET 市场而言，引入配额拍卖有利于降低 CET 价格，提高其流动性和减排效果，这是提高 CET 市场有效性的配额分配机制之一。然而，配额拍卖将增加减排成本，降低成本效益。因此，为了提高中国 CET 制度的制度绩效，有必要进行 L-CTI，以缓解配额拍卖带来的减排成本增加，从而提高国家 CET 市场的减排效果和成本效益。
