何为LP，即Limited Partnership，原文为“A limited partnerp has at least one general and one limited partner. General partners in a limited partnership are like general parters in a general partnership, which includes personal liability for the debts of business. Limited and general partners are owners and enjoy the tax benefit of being partners in a partnership. By statute limited partners are not liable for the debt of business...they do not have management rights in their status as limited partners... ”中文意思就是，LP即中 国合伙企 业法里面有限合伙概念，既有普通合伙人，又有有限合伙人，有限合伙人享受合伙制的优越性（如单一征税），同时担任有限责 任，但是没有管理权。

LLLP即Limited Liability Limited Partnership. LLLP is an entity authorized by statute...in which limited liability is extended to general partners of a limited partnership in the same manner as it is to partners in an LLP. In all other respects the LLLP is like a regular limited partnership. 即，LLLP就是将LP中的普通合伙人也搞得像LLP中的合伙人一样，既有管理权，又享受有限责任，但是保留一部分只有有限责任，却没有管理权的有限合伙 人。

LLC即Limited Liability Company, 初看很像中文的有限责任公司，但是，LLC is a form of doing business as an unincorporated entity. It offers owners the benefits of limited liability, taxation as a partnership, and management flexibility. Liability is limited in the sense that owners are not liable for the debts of the business and in that respect are in a similar position to shareholders of a corporation.
根据元照英美法字典解 释，corporation 指法人或公司，incorporation 指法人设立（名词），unincorporated 指非法人的，非注册的
即， 在美国法，LLC是指不具备法人资格的有限责任“公司”，此含义与中国公司法的有限责任公司截然不同，美国LLC是合伙人（有限责任，单一征税）＋法人股 东有限责任的结合体＋弹性管理制度。

（A limited liability company (abbreviated L.L.C. or LLC) in the law of the vast majority of United States jurisdictions is a legal form of business company that provides limited liability to its owners. Often incorrectly called a "limited liability corporation" (instead of company), it is a hybrid business entity having certain characteristics of both a corporation and a partnership or sole proprietorship (depending on how many owners there are). An LLC, although a business entity, is a type of unincorporated association and is not a corporation. The primary characteristic an LLC shares with a corporation is limited liability, and the primary characteristic it shares with a partnership is the availability of pass-through income taxation. It is often more flexible than a corporation and it is well-suited for companies with a single owner.）
