Present-day supply-side structural reform in China places an abundance of emphasis on environmental protection. In this paper, we re-measure the upstreamness of Chinese enterprises in global value chains as described by Ni Hongfu (2022). Subsequently, the impact of environmental regulations on the global value chain position of Chinese firms is studied in depth, using the cleaner production standards promulgated and implemented by the Chinese government in 2003 as a quasi-natural experiment, taking a time-varying difference-in-differences (DID) approach. The data sources employed include the Cleaner Production Standard Implementation Industry Directory, the World Input-Output Database (WIOD), the China Industrial Enterprise Database, and the China Customs Import and Export Database. This research discovered the following: First, adopting cleaner production standards significantly improves Chinese enterprises' positions in the global value chain-a conclusion that holds up to a number of robustness tests. Second, in terms of firm size, capital intensity, ownership characteristics, and government subsidies, there exists a noticeable heterogeneity in the promotion of the adoption of cleaner production standards for the improvement of Chinese enterprises' global value chain position. Third, the implementation of cleaner production standards stimulates the upgrading of Chinese enterprises' global value chain position, primarily through the entry and exit impacts, product-switching effect, and innovation compensation effect. The following proposals for policy can be implemented in light of the findings of this paper: "upstream prevention" strategies in the development of future environmental protection and trade policies should be advocated; nuanced and stratified environmental policies should be meticulously constructed; a mix of policies should be employed to bolster the institutional support for green environmental regulations; the integration of environmental governance into the evaluation framework should be emphasized; the creation of an innovation-oriented environmental governance system should be expedited. In conclusion, the findings of this research provide empirical evidence on the role of environmental regulations in coordinating ecological development and strengthening the position of Chinese enterprises in global value chains, which may assist other developing nations in making the transition to a path of high-quality growth.
