Abstract: 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.

Key words: carbon tax, capital restraint, remanufacturing, production decision, financing
