A research is conducted on the impacts of remanufacturing rate, capital constraints and carbon taxes on manufacturing/remanufacturing production decisions. First, a manufacturing/ remanufacturing production decision model is established with capital constraints under the carbon tax policy, and then considering production decision capital constraints and financing, new products, remanufactured goods, expected profits and carbon emissions are researched and compared in two cases; finally, the influences are evaluated through a case study of the remanufacturing rate, consumer preferences and the unit carbon emission tax of the recovered products on the optimal yield, the expected profit and the carbon emission. The results show that, considering the financial factors, whether the recovery rate is sufficient in different circumstances or the threshold is different, under the capital constraints, the higher the recovery rate the better; With the increase of consumer preferences, as the remanufactured products by the manufacturer increase, the production of new products decreases, and the expected profits increases with the reduction of carbon emissions; the increase in carbon taxes will reduce the production of new products and increase the production of remanufacturers. However, when the carbon tax is too high, the production of remanufacturers will gradually decrease.%以制造/再制造混合系统为研究对象,分析了碳税政策下资金存在约束的生产决策间题.首先建立了碳税政策下初始资金存在约束的制造/再制造生产决策模型;然后考虑初始资金不足进行融资情形下的生产决策,求解并对比两种情形下新品、再制造品、期望利润和碳排放量的变化;最后通过算例分析给出再制造率、消费者偏好和单位碳排放税额对最优产量、期望利润和碳排放量的影响.研究表明,在考虑资金因素时,不同情形下回收量是否足够的回收率临界值不同,资金约束下,回收率越高越好;随着消费者偏好的提高,制造商生产的再制造品产量增加,新品的产量减少,同时期望利润增加,碳排放量减少;碳税的增加会降低新品的产量和增加再制造品的产量,但碳税过高时,再制造品的产量也会逐渐降低.
