Roles of International Environmental Law in China's Environmental Productivity: Challenges and Implications.

International environmental law is the basic charter for dealing with international environmental issues, and it plays an important role in international environmental governance. In recent years, China's economy has achieved great development, but environmental problems are also very prominent. International environmental law provides a basic reference for China's environmental governance, but it also brings challenges to the development of China's environmental productivity to a certain extent. At the same time, due to the unique dominant position of international environmental law, it has played a certain restrictive role in the development of China's environmental productivity. Based on this, in order to promote the sustainable development of China's economy, this paper took China's industrial and agricultural development as the research object. This paper has conducted research on China's industrial and agricultural environmental productivity, aiming to explore the role of international environmental law in China's environmental productivity. The article first analyzed the limitation of international environmental law on China's environmental productivity, and then on this basis, the article conducted a numerical simulation of China's industrial and agricultural environmental productivity. Finally, starting from the actual development situation, the paper aimed to find out the numerical deviation of China's environmental productivity changes through quantitative analysis. In the course of the research on environmental productivity development, the article found a strong correlation between environmental productivity and international environmental law in China. The correlation between environmental productivity and international environmental law reaches 59.93% in South China and 61.02% in North China. Also, after a series of comparative analyses, the article finds that changes in climate characteristics can exacerbate the regulation of China by international environmental law and seriously affect China's economic development. In this case, China's economy declined by 2.6% year-on-year, which further pushed China to practice sustainable development strategies. This shows that it is essential to study the relationship between international environmental law and China's environmental productivity.
