计算结果表明,当一个地区政府政策引导适当,对环境重视强度高时,该地区的生态效率就会相对有效。当一个地区经济发展过快时,政府正常的关于发展循环经济的政策引导就会产生时间滞后的效应,生态效率就由有效转而显示为无效,则此时政府就要采取创新性的环境引导政策,并使该政策与经济发展相适应以达到生态有效率。 The results show that the eco-efficiency of the region will be relatively effective when the guidance of a region government policy is appropriate and the emphasis on environment is high. When a region’s economy develops too fast, the government’s normal policy guidance on the development of circular economy will have the effect of time lag, and the ecological efficiency turns from effective to ineffective. At this time, the government should adopt an innovative environmental guidance Policy and adapt the policy to economic development to achieve eco-efficiency.
