通过对对公共物品的划分,分别针对人造公共物品和自然公共物品提出了供给主体与管理主体的确立提出建议。通过供给主体多元化和管理主体明确化来实现公共物品有效(供需相契、供需平衡、品质提升)的供给,推动整个社会福利的增加。 Through the division of public goods, we put forward suggestions on the establishment of supply subject and management subject respectively for man-made public goods and natural public goods. Through the diversification of supply entities and the clarification of management entities, the supply of public goods effective (supply and demand, balance of supply and demand, quality improvement) will be realized and the increase of social welfare as a whole will be promoted.
