The production and trade activities of global value chains (GVC) increasingly contribute to the gross domestic product (GDP) of developing countries. However, while the development of domestic economies brings about technological progress, it also may have negative consequences such as environmental pollution. Technological progress can be conducive to reducing pollution emissions. Our motive is to realize the dual effects of technological progress and energy saving and emission reduction in developing countries' participation in the global value chain through research on GVC, technological progress and environmental pollution. Improving environmental quality through technological advances and reducing the adverse effects of inequality in trade status, enabling developing countries to obtain dividends from participating in the value chain as much as possible, and mitigating the adverse effects of environmental pollution during development. And lay the policy foundation for developing countries to go green. However, most of the current researches focus on the relationship between GVC and technological progress or GVC and environmental pollution, and the research on the relationship between the three is scarce. We use the WIOD database to try to find the relationship between developing country global value chain participation, technological progress and environmental pollution. Wang's method for GVC embedding is adopted for empirical research on input and output, energy utilization, high-skilled labor ratio, and pollution emissions in five typical developing countries, namely, Brazil, Russia, India, China, and Mexico. The relationships among the degree of participation in GVC, technological progress, and environmental pollution is studied from the perspective of industries in each country. The outcomes indicate that there is a value chain threshold in developing countries. When the degree of participation in a value chain is lower than the threshold, technological progress can result in an increase in pollution; otherwise, technological progress can reduce emissions. These results provide a theoretical basis and practical suggestions for developing countries to realize their own energy conservation, emission reductions, and green development while participating in globalized value chains. However, because the data related to the WIOD database is limited to 1995-2009, there are a few flaws in data integrity, which is also a challenge we face.
全球价值链（GVC）的生产和贸易活动越来越多地为发展中国家的国内生产总值（GDP）做出贡献。然而，在国内经济发展带来技术进步的同时，也可能带来环境污染等负面影响。技术进步可以有助于减少污染排放。我们的动机是通过对 GVC、技术进步和环境污染的研究，实现发展中国家参与全球价值链的技术进步和节能减排的双重效应。通过技术进步提高环境质量，减少贸易地位不平等的不利影响，使发展中国家尽可能从参与价值链中获得红利，并减轻发展过程中环境污染的不利影响。为发展中国家走向绿色发展奠定政策基础。然而，目前的研究大多集中在 GVC 与技术进步或 GVC 与环境污染之间的关系上，对三者之间的关系研究较少。我们使用 WIOD 数据库试图找出发展中国家全球价值链参与度、技术进步和环境污染之间的关系。采用 Wang 的 GVC 嵌入方法，对巴西、俄罗斯、印度、中国和墨西哥五个典型发展中国家的投入产出、能源利用、高技能劳动力比例和污染排放进行实证研究。从各国产业角度研究 GVC 参与度、技术进步和环境污染之间的关系。结果表明，发展中国家存在价值链门槛。当价值链参与度低于门槛时，技术进步会导致污染增加；否则，技术进步可以减少排放。这些结果为发展中国家在参与全球化价值链的同时实现自身节能减排和绿色发展提供了理论依据和实践建议。然而，由于 WIOD 数据库相关数据仅限于 1995-2009 年，数据完整性存在一些缺陷，这也是我们面临的挑战。
