摘要
除了税收手段直接调整人均收入差距之外,政府可利用投资配置来影响生产过程,进而调整人均收入差距。在总量封闭经济的框架下,本文以人均收入差距最小化为目标,通过引入多地区多产业Cobb-Douglas生产函数、劳动一资本比率、资本时变率,改造最优经济增长模型。实验表明,通过权衡不同地区、不同产业的重要程度,调整投资在不同地区、不同产业之间的配置比率,政府可缩小人均收入差距。
The government can utilize investment allocation to affect production to further modulate income per capita gap in addition to imposing taxation directly. Under the aggregatie close economy framework, the optimal economic growth model is reconstructed with the objective of income per capita gap minimization by introducing multi - region and multi - sector Cobb - Douglas production function, labor - capital ratio, and the time rate of capital change. Case study shows that the government can lessen income gap per capita by weighing the importance of different regions and sectors and adjusting the allocation proportions of investment in these regions and sectors.
