There is a consensus among the empirics regarding the positive role of renewable energy in mitigating the effects of climate change. Hence, it is vital to search for the factors that can promote renewable energy demand. As a result, this analysis investigates the impact of educational attainment, environmental law, and innovation on renewable energy consumption (REC) in China. From empirical estimates, we confer that the long-run estimates attached to the environment-related taxes and environmental policy stringency are positive and significant, implying that both these factors increase the REC in China in the long run. Similarly, the estimated coefficients of environment-related technologies and patent applications are significantly positive, confirming that environmental and other technologies give rise to REC in the long run. Likewise, the long-run estimates of education are significantly positive in both models, which confer that REC increases along with an increase in average years of schooling. Lastly, the estimates of CO₂ emissions are significantly positive in the long run. These results imply that policymakers should invest in research and development activities that are crucial for promoting eco-innovation and renewable energy demand. In addition, strict environmental laws should be introduced to induce firms and businesses to invest in clean energy.

Optimizing export growth patterns and improving the quality of export trade have become prominent issues that need to be addressed urgently in the context of increasing global economic uncertainty. This study utilizes matched data from the CEPII database (1995–2020) and WTO tariff database, adopts a product-level perspective based on the triple margins of exports, and uses an individual-time two-way fixed-effects model to investigate the impact of import trade liberalization on China's export growth pattern. The research findings are as follows: (1) Increasing levels of import trade liberalization are beneficial for enhancing the extensive margin, intensive margin, and quantity margin of products, while exerting a restraining effect on the price margin. This strengthens the price advantage of Chinese products, indicating that import trade liberalization helps optimize China's export growth pattern. (2) Compared with the intensive margin, import trade liberalization has a more significant promoting effect on the extensive margin. (3) The conclusions drawn from heterogeneity analysis suggest that trade liberalization has a more pronounced effect on the extensive margin, intensive margin, and quantity margin of products in medium-high technology industries, differentiated products, and intermediate goods. This study holds important theoretical and practical significance for evaluating the economic benefits of expanding imports, optimizing China's export growth pattern, and improving the quality of export trade.
