借壳上市，英文表达为back door listing。是一个金融术语，指一家母公司（集团公司）通过把资产注入一家市值较低的已上市公司（壳：shell），得到该公司一定程度的控股权，利用其上市公司地位，使母公司的资产得以上市。

买壳上市，英文表达为go public through buying，欲买壳的企业先收购控股一家被选为“壳”公司的上市公司，然后将买壳企业的经营性资产、重要子公司等通过出售或置换、定向增发暨吸收合并或控股合并等形式注入该上市公司，从而实现上市。

总结二者的异同：

相同点：不管是买壳上市还是借壳上市，他们都是对“壳”公司的资源进行重新分配的活动，从而达到自己上市的目的。

不同点：买壳上市是需要未上市公司需要提前获得对一家上市公司的控股权，而借壳上市则是已经有了对公司的控股权。

参考双语例句：

大部分的股票交易异常波动的现象会伴随着市场上定向增发、资产重组、整体上市和借壳上市的传闻一起出现。

Many abnormal fluctuation phenomena occurs together with the rumors of private offering, asset reconstruction, "on listed as a whole" and "back-door listing".

One of the major upsides of going through a back door listing is that it is considered a cost-effective measure for a private firm to go public. Because it can strike up a deal with an already public company, it doesn't have to go through the expenses of regulatory filings or funding to go public.Private firms may also inject life into a troubled company without the need to raise more money from the market.

借壳上市的好处：

借壳上市的主要好处之一是，它被认为是私营公司上市的一种具有成本效益的措施。因为它可以与一家已经上市的公司达成交易，它不需要通过监管申报或融资的费用就可以上市，私营公司也可以为陷入困境的公司注入活力，而不需要从市场上筹集更多资金。
