<p>Green economy requires enterprises to comply with environmental regulations, which increases the enterprises risk-taking level and ultimately affects the investment decision of enterprises. By constructing multiple linear regression equations with four dimensions of enterprise risk-taking level as dependent variables and three types of environmental regulations as independent variables, the data of listed chemical companies in China are used for the empirical test. Empirical results show that command environmental regulation has a significant promoting effect on the risk-taking level of capital, talent, and product, but has no significant impact on the technology risk-taking level. Market environmental regulation can effectively enhance the risk-taking level of capital and talent, but has no significant impact on the risk-taking level of technology and product. Voluntary environmental regulation only has a significant effect on enhancing the capital risk-taking level. The existing environmental regulation system can be optimized, focusing on the driving function of environmental regulation on the technology risk-taking level, activating the role of voluntary environmental regulation, and ultimately improving the enterprise risk-taking level.</p>
