论休闲的边际投资倾向

人的终极稀缺资源是时间。人的生命时间由平均预期寿命框定。生命时间有其内在结构,其中,休闲时间占重要比重。从经济学的角度看,休闲和收入有密切关系,收入和消费、储蓄、投资又有密切关系。由于投资中的人力资本投资对休闲有重要影响,因而根据人力资本投资时间与休闲时间的基本关系,可提出"休闲的边际投资倾向(LMPI)"这一概念。通过对这一概念的分析和函数曲线的比较,可发现一些有趣现象,得出一些与休闲有关的重要结论。这些结论和方法在休闲问题的量化研究中,具有广泛的应用前景。

On the Leisure Marginal Propensity to Invest

For man,the ultimate scarce resource is time.Man’s life time is defined with average life expectancy.Life time has its inherent structure,where leisure time takes up a significant proportion.From the economic perspective,leisure is closely associated with incomes,which is related with consumption,savings and investment.Investments of human capital have important influences on leisure;therefore according to the basic relation between the time of human capital investment and leisure time,it is plausible to propose a concept "leisure marginal propensity to invest(LMPI)".Through the analysis of it and function curve comparison,some interesting phenomena have been found,and important conclusions are drawn.These conclusions and methods have great potential of application in the quantitative research of leisure.
