随着人民生活水平的提高，生态环境日益受到重视。进入２１世纪，产品并不单单是靠市场需求来生存，环境保护的否决权决定企业是否拥有生产许可证。能否生产，能否继续发展，不仅仅决定于有无市场需求，关键在于生产是否产生污染，污染治理结果是否仍对社会和人民生活产生有害 With the improvement of people’s living standards, the ecological environment has been increasingly valued. In the 21st century, products do not rely solely on market demand for survival. The veto power of environmental protection determines whether a company has a production license. Whether or not it can produce and whether it can continue to develop depends not only on market demand, but also on whether production produces pollution and whether pollution control results are still harmful to society and people’s lives.
