摘　　要：公共产品和私人产品的适度产出比例是现代市场经济中促进国民社会福利提升的发展机制,由这一比例决定的公共投资规模是社会福利提升的社会基础。东亚各国经济若保持长期持续均衡增长,其公共投资应纳入这一发展机制。依据这一原理建立中国和日本的社会福利生产函数,比较这一比例对二者社会福利的影响。中国社会福利处于规模收益上升阶段,人均财政支出的增速高于人均消费增速,而人均消费支出的社会福利弹性系数高于人均财政支出,后者对前者有一定的外部性作用;日本的社会福利处于成熟阶段,极易受国际经济的影响,人均财政支出主要起调节和平抑经济周期的作用,公共产品与私人产品的相互融合影响社会福利,人均消费增速低于人均财政支出,但其产出弹性高于人均财政收入,经济体系受国际市场摩擦负外部性的极大影响。为此,应从调整公共产品和私人产品的投资比例入手,实施财政支出政策以促进东亚各国社会福利的提升。Keeping a moderate proportion of public products and private products is the development mechanism of promoting social welfare in the modern market economy. The public investment scale determined by the proportional relationship is the social basis for guaranteeing the social welfare improving. If the economies of East Asian countries maintain long-term continuous balanced growth, the public investment should be included in the development mechanism. Based on this principle we established the Chinese and Japanese social welfare production function, compared the influence on social welfare income from the proportional relationship. China＇ s social welfare is in the stage of increasing returns to scale, the fiscal expenditure per capita growth rates is higher than the growth of per capita consumption, and the social welfare elasticity coefficient of per capita consumption expenditure is higher than the fiscal expenditure＇ s, the latter to the former has some externalities actions. Japan＇ s social welfare function is in mature stage, which is easy to be affected by the fluctuation of the international economy, the fiscal expenditure per capita has a main function of adjusting and stabilizing economic cycle, the integration of the public products and private products works on the social welfare, the growth speed of per capita consumption expenditure is lower than the per capita fiscal expenditure, but the output elasticity is higher than per capita Revenue, Japan＇ s economic system is being seriously affected by the negative externalities of international market friction. Therefore, we should get down to adjusting the proportion of the public products and private products, to implementing fiscal expenditure policy to promote social welfare of the East Asian countries improving continuously.
