公共产品论发展初期,人们认为公共产品应不分层次、不分情况全部由政府供给。20世纪70年代科斯发表了《经济学中的灯塔》(1974)一文,在理论上首次提出公共产品的市场供给。其后,公共产品的市场供给逐渐得到理论界的广泛关注,政府和市场的供给责任划分也就相应地成为该领域研究的重点内容,公共品的需求弹性理论可以为这一问题的探索提供新的研究视角。 In the early days of the development of public goods theory, people believed that public goods should be given no horizons and provided by the government, regardless of circumstances. In the 1970s, Coase published the article “Lighthouse in Economics” (1974), which theoretically proposed the market supply of public goods for the first time. Since then, the market supply of public goods has gradually drawn the attention of theorists, and the division of government and market supply responsibilities has accordingly become the focus of research in this field. The demand elasticity theory of public goods can provide a new way for the exploration of this issue Research perspective.
