摘要
在最优增长模型基础上放松效用贴现因子不变的假设,考虑改善性支出和人口老龄化对时间偏好的影响,讨论稳态和平衡增长道路,分析居民支出结构的影响因素。运用微观调研数据,检验了理论模型的假说。研究发现,收入、财产等衡量经济条件的指标对改善性支出占比有正向推动作用,年龄的因素对于全体居民和老龄居民的消费结构影响不同,健康只影响医疗支出,而受教育程度越高,居民越倾向于增加改善性支出比重。扩大老年消费的主要途径是提高收入,为老龄人口的生活提供必要的保障。
On the basis of the optimal growth model, the constant discount factor assumption was relaxed. Through changing time preference, improvement expenditure and population aging may influence the steady-state consumption and balanced growth path. Using the micro survey data, the hypothesis of the theoretical model was tested. It is found that income and property have a positive role in promoting improvement expenditure, age factors have different effects for all residents and the elderly consumption structure, health affects only medical expenditure, residents with higher education tend to increase the proportion of improvement expenditure. The main way to expand consumption of the elderly could be to improve income and to provide necessary guarantee for the aging population.
