所谓循环经济,本质上是一种生态经济,它要求运用生态学规律而不是机械论规律来指导人类社会的经济活动。与传统经济相比,循环经济的不同之处在于:传统经济是一种“资源—产品—污染排放”单向流动的线性经济,其特征是高开采、低利用、高排放。循环经济要求把经济活动组织成一个“资源—产品—再生资源”的反馈式流程,其特征是低开采、高利用、低排放。所有的物质和能源要能在这个不断进行的经济循环中得到合理和持久的利用,以把经济活动对自然环境的影响降低到尽可能小的程度。
The so-called circular economy is essentially an ecological economy, which requires the use of ecological laws rather than mechanical laws to guide the economic activities of human society. Compared with the traditional economy, the difference of circular economy is that the traditional economy is a one-way flow of “resource-product-pollution discharge” linear economy characterized by high production, low utilization and high emission. Recycling economy requires the economic activities organized into a “resource - product - renewable resources,” the feedback process, which is characterized by low mining, high utilization, low emissions. All material and energy resources should be able to be reasonably and enduringly utilized in this ongoing economic cycle to reduce the impact of economic activities on the natural environment to the minimum extent possible.
