joint stock company 合股公司（暫譯）

根據InvestorWords.com的定義，joint stock company是指：

A company which has some features of a corporation and some features of a partnership. The company sells fully transferable stock, but all shareholders have unlimited liability.

根據這個定義，company和corporation其實是不同的。但怎麼不同，有待進一步研究。
