传统经济是由“资源——产品——污染排放”的物质单向流动的经济。即人们把地球上的物质和能源开采出来 ,经过生产、加工和消费过程 ,又把污染和废物大量地排放到环境中去 ,对资源的利用是粗放的、一次性的 ,导致了许多自然资源的短缺与枯竭 ,并酿成了灾难性的环境污染后果——诸如水源、空气污染和垃圾堆放、沙尘暴等。与此不同 ,循环经济则是建立在物质不断循环利用 ,循环替代 ,循环净化基础上的经济发展模式 ,使经济活动按照自然生态系统的规律 ,组成一个“资源——产品——再生资源”的物质反复循环流动过程 ,使整个经济系统以及生产和消费的过程基本上不产生或者只产生很少的废物。循环经济学的特征是自然资源的低投入、高利用和废弃物的低排放 ,从而根本上消解长期以来环境与经济发展的尖锐冲突
The traditional economy is a one-way flow economy of “resource-product-pollutant discharge” substances. That is, people extract the material and energy from the earth, and after production, processing and consumption, release a large amount of pollution and waste into the environment. The utilization of resources is extensive and one-off, resulting in many natural resources Shortage and depletion, and lead to disastrous environmental consequences - such as water, air pollution and dumping, dust storms and so on. In contrast, circular economy is based on the continuous development of material recycling, recycling, recycling based on the economic development model, so that economic activities in accordance with the law of natural ecosystems to form a “resource - products - renewable resources” The process of material circulation is repeated and the entire economic system, and the process of production and consumption, are essentially not generated or produce very little waste. Circular economy is characterized by low investment in natural resources, high utilization and low emissions of waste, thus fundamentally dissolving sharp conflicts between environmental and economic development
