The study aims to identify the impact of technological progress on environmental pollution within the framework of Egypt’s participation in Global Value Chains (GVCs), using the Threshold Regression method during the period from 1990 to 2018, which is the most recent data published in the Global Value Chain database. For (UNCTAD-Eora). The study found that the technological level has a positive impact on environmental pollution. When Egypt's low participation in global value chains is below the threshold level, which is equivalent to 5.1 million dollars, while the impact of technological progress on environmental pollution becomes negative above that value, and the deepening of capital and highly skilled labor have a negative impact on environmental pollution emissions. The intensity of energy use in manufacturing industries and the proportion of industrial value added to GDP have a positive impact on environmental pollution. These results provide a theoretical basis for making practical proposals to achieve green development while participating in global value chains. Developing countries, including Egypt, should: Increase participation in global value chains, enhance their exports, and increase their added value in global industries. So that you can improve the quality of the environment through technological progress and achieve steady economic growth.
