Abstract: This paper uses theoretical modeling and empirical data to study the relationship between environmental legislation control and the domestic valueadded rate of Chinese firm's exports. It turns out that environmental legislation and control can help increase the domestic valueadded rate of Chinese firms' exports. Mechanism analysis proves that, on the one hand, the “cost effect” of strengthening environmental legislation control makes directly constrained companies look for other alternative elements. The magnitude of this substitution effect depends on the degree of dependence of the company on polluting resources. The “innovation effect” affects the cost bonus of firms by changing the production efficiency. Both effects affect the domestic valueadded rate of exports. On the other hand, environmental legislative control increases the lower bound of the productivity of domestic firms exporting to foreign markets, and makes indirectly restricted firms change their prices, which in turn acts on the domestic valueadded rate of exports. Expansion studies show that strict regional law enforcement will help expand the positive impact of environmental legislation and control on the domestic valueadded rate of exports of firms with a low degree of dependence on polluting resources.
