在低碳经济背景下,同时考虑政府征税和补贴以及消费者环保意识,研究了生产商的低碳技术选择问题,对比分析了生产商以现有技术或低碳技术或同时采用现有技术和低碳技术的多技术生产时的最优决策和碳排放,并探讨了消费者环保意识、碳税和补贴对生产商三种技术的碳排放和利润的影响。研究发现,当政府低碳技术补贴较大且消费者环保意识较强时,生产商采用多技术进行生产,否则,生产商以现有技术进行生产；此外,生产商利用市场细分策略,使得以多技术生产的利润总是比仅采用低碳技术生产的利润要高；另外,消费者环保意识水平的提高并不总能降低生产商的碳排放,而碳税的增加却总能降低生产商的碳排放。

Under the background of low-carbon economy, in order to study the manufacturer’s choice of low carbon technology, this paper consider government’s tax, subsidies and consumers’ environmental awareness simultaneously. The manufacturer’s optimal decisions, total carbon emissions of dirty technology, low-carbon technology and multi-technology were obtained and analyzed, moreover, the impact of consumers’ environmental awareness, carbon tax and subsidies on the manufacturer’s total carbon emissions and profit under three technologies were examined. It shows that manufacturer will choose multi-technology when the subsidies of low carbon technology is big and consumers’ environmental awareness is strong, otherwise, manufacturer will not choose low carbon technology; through implementing market segmentation, the manufacturer’s profits of multi-technology always higher than produced by low carbon technology only; furthermore, the increase of consumers’ environmental awareness cannot always lead to the decrease of carbon emissions, however, the increase of carbon tax can decrease manufacturer’s carbon emissions effectively.
