The Air Pollution Prevention and Control Action Plan (APCP) is an important pollution control policy formulated by the Chinese government to promote green development. However, there are few studies of its impact. Based on a province-level panel dataset from 2007 to 2017, we use a three-hierarchy meta-frontier slack-based data envelopment analysis (SBM-DEA) model and the global Malmquist (GM) index to estimate the green total factor productivity (GTFP) of China's chemical sub-industries. Next, we use the difference-in-differences (DID) method to explore the effect of the implementation of the APCP in 2013 on the GTFP of China's chemical industry. We find an increasing trend in the GTFP of China's chemical industry between 2007 and 2017. A decomposition of the change in GTFP shows that technical progress was the main driving factor and management inefficiency was the main inhibitory factor. The APCP had a significant positive effect on GTFP. Overall, in the post-implementation period, the increase in the GTFP of the treatment group was approximately 7.9% greater than in the control group. The APCP also significantly improved the technical efficiency change index. A dynamic effect analysis shows that the positive effect of the APCP on GTFP had an inverted U-shaped trend. A series of robustness tests, including counterfactual, re-grouping, and quasi-DID tests, suggest that our findings are reliable. In addition, changes in exports, capital deepening, and energy prices all significantly improved the GTFP of China's chemical industry.
《大气污染防治行动计划》（APCP）是中国政府为促进绿色发展而制定的一项重要污染控制政策。然而，目前关于其影响的研究较少。本研究基于 2007 年至 2017 年的省级面板数据集，采用三层次超效率 slack 基数据包络分析（SBM-DEA）模型和全局 Malmquist（GM）指数来估计中国化工子行业的绿色全要素生产率（GTFP）。然后，我们使用差分法（DID）来探讨 2013 年实施 APCP 对中国化工行业 GTFP 的影响。研究发现，2007 年至 2017 年间，中国化工行业的 GTFP呈上升趋势。GTFP 变化的分解表明，技术进步是主要的驱动因素，管理效率低下是主要的抑制因素。APCP 对 GTFP 有显著的正向影响。总体而言，在实施后期，处理组的 GTFP 增长率比对照组高约 7.9%。APCP 还显著提高了技术效率变化指数。动态效应分析表明，APCP 对 GTFP 的正向影响呈倒 U 型趋势。一系列稳健性检验，包括反事实、重新分组和拟 DID 检验，表明我们的发现是可靠的。此外，出口、资本深化和能源价格的变化均显著提高了中国化工行业的 GTFP。
