Abstract：
Over the last four decades, the Chinese government has predominantly employed emission fees as a regulatory strategy to mitigate pollution from firms. However, the effectiveness of escalating emission fee rates on the emission levels of Chinese firms has not been examined. This study utilizes data from more than 80,000 Chinese firms spanning 2004-2013, employing difference-in-differences models to assess the effects of rising emission fee rates on firm emissions. The findings indicate the following: (1) Increased emission fee rates substantially reduce sulfur dioxide and chemical oxygen demand emissions among Chinese firms; (2) These heightened fees encourage firms to implement both end-of-pipe treatment and source control for sulfur dioxide and end-of-pipe treatment for chemical oxygen demand; (3) The emission reduction effects vary according to firm ownership and size. This research offers empirical evidence on the efficacy of emission fee systems and provides valuable insights for developing market incentive-based environmental regulations in the future.
摘要：
在过去的四十年里，中国政府主要采用排放费作为减轻企业污染的监管策略。然而,提高排放费用率对中国企业排放水平的有效性尚未得到检验。这项研究利用了2004-2013年80,000多家中国公司的数据，采用差异差异模型来评估排放费用率上升对公司排放的影响。研究结果表明：（1）提高排放费用率大大降低了中国企业的二氧化硫和化学需氧量排放量；（2）这些提高的费用鼓励企业对二氧化硫实施管道末端处理和源头控制，并对化学需氧量实施管道末端处理；（3）减排效果因企业所有权和规模而异。这项研究为排放费系统的有效性提供了经验证据，并为将来制定基于市场激励的环境法规提供了宝贵的见解。
