Corporate social responsibility can be divided into three levels: The first level is the regulatory level, which can ensure the normal existence of the enterprise, including compliance with laws, paying taxes according to law, and controlling the emission of harmful substances. The second layer is the interest layer, which contributes to the long-term development of the company, including safeguarding the rights and interests of consumers and employees, being honest and trustworthy to suppliers and sellers, ensuring the interests of investors, and protecting the environment. The third layer is the moral layer, which is the company's feedback to society, including conservation of resources, responsibility to community residents and participation in charity.
