今天我们将继续阅读由郭强等学者撰写的文章《消费者预期后悔对汽车碳排放及其利润的影响》，上一期我们阅读了文章的模型结果分析以及数值案例分析进行阅读，本期进入结论和展望的阅读。
Today we will continue to read the article "The Effect of Consumer Expectation Regret on Automotive Carbon Emissions and Their Profits" written by Qiang Guo and other scholars. In the last issue we read the model results analysis of the article as well as the numerical case study for reading, and this issue goes into the conclusion and outlook reading.
02结论与展望
【结论】本篇文章同归对比存在和不存在消费者预期后悔的情况下，研究了预期后悔对价格，需求，碳排放造成的影响。作者共得出三点结论：
（1）燃油汽车商的利润、需求等受到了预期后悔带来好处，从价格的竞争中得到了缓冲；但新能源汽车的利润需求等却在降低，只有当碳排放较高的时候利润才会增加。
（2）碳排放量会在存在消费者预期后悔时更高，且企业自主决策低碳技术时，碳排放量随着预期后悔的增大而增加。
（3）对于新能源汽车来说，重复购买下的预期后悔增加会使得消费者剩余增大；但是在转换购买后悔下，则要考虑碳排放量的高低，越高则消费者剩余越小，越低则消费者剩余越大。
[Conclusion] This article homogeneously compares the presence and absence of consumer expected regret and investigates the effects caused by expected regret on price, demand, and carbon emissions. The authors conclude three points in total.
(1) The profits and demand, etc. of fuel car dealers are benefited by expected regret and cushioned from price competition; however, the profits and demand, etc. of new energy vehicles are decreasing, and profits increase only when carbon emissions are high.
(2) Carbon emissions will be higher when there is consumer expected regret, and carbon emissions increase with expected regret when companies make their own decisions on low-carbon technologies.
(3) For new energy vehicles, the increase of expected regret under repeated purchase will make consumer surplus increase; however, under switching purchase regret, the higher the carbon emissions, the smaller the consumer surplus, and the lower the consumer surplus, the larger the consumer surplus.
【展望】作者指出未来可以将消费者异质性和预期后悔下的碳排放量联合考虑；除此之外，也应该结合更多现实的因素进行研究，比如：信息不对成、风险规避等。
[Perspective] The authors point out that carbon emissions under consumer heterogeneity and expected regret can be jointly considered in the future; in addition, more realistic factors should also be studied, such as: information misalignment, risk aversion, etc.
03学习心得这篇文章和我以前阅读的关于预期后悔的文章研究有所不同，他将后悔分为了转换后悔和重复后悔，并在模型中进行了体现，基于两种不同种类的后悔进行了研究，扩展了自己的思考方向，有借鉴学习的意义。
This article is different from the studies I have read before on anticipatory regret. He divides regret into conversion regret and repetitive regret, and reflects them in the model, based on two different kinds of regret, expanding the direction of his own thinking and having the significance of learning from them.
