摘要： 针对传统消费未能考虑对其具有重要支撑作用的自然资本，考虑资本、环境资源及绿色消费变动的情况下，引入环境资源存量E，将绿色消费V作为可被利用的公共产品，建立环境资源约束下以社会福利最大化为目标的最优绿色消费模型，利用最优控制理论，求解均衡状态下最优绿色消费路径的解析解，对绿色消费的影响因素资本弹性α、环境资源承载力ē、环境污染系数ε和绿色消费初值V0在不同情况下的最优绿色消费路径进行数值仿真，结果表明：(1) 绿色消费V在V0小于VC时关于时间t单调递增，在V0大于VC时单调递减，且均收敛于VC；(2) ē与绿色消费V正相关，但与绿色消费占比V/(C+V)负相关，且对传统消费的作用更显著；(3) α与绿色消费占比V/(C+V)负相关且在α=0.18时绿色消费占比V/(C+V)增速最快，但ε与绿色消费占比V/(C+V)正相关.

Abstract: To address environmental degradation and resource exhausting caused by traditional consuming pattern, an optimal green consumption model aiming to maximize social welfare has been built to uncover optimizing paths of green consumption under the equilibrium state. In the proposed mode, environmental resources stock E has been taken into account with a constraint condition of environmental externality. Simulation results under divergent capital elasticity α, the carrying capacity of environmental resources ē, and coefficient of environmental pollution ε and initial value of the green consumption V0 have been drawn based on the proposed model. The findings indicate that: (1) the green consumption V increases and decreases monotonically over time when V0 is lower and higher than VC, respectively, and converges to VC; (2) ē is positively correlated to the green consumption V, yet is negatively correlated to the ratio of green consumption V/(C+V), which plays more significant role in greening the traditional consumption pattern; (3) α is negatively correlated with the ratio of the green consumption V/(C+V), and reaches its peak growth rate when α=0.18. However, a positive correlation exits between the environmental pollution coefficients and the ratio of the green consumption.
