摘要：劳务派遣单位是劳务派遣中的核心角色，其法律制度的完善有利于发扬劳务派遣的优势与价值。具体来看，劳务派遣单位的市场准入制度、义务和责任三个方面分别从成立前、运营中和造成损害后对派遣单位起到制约作用，对派遣单位发展的规范性十分重要。文中对劳务派遣单位的市场准入制度做了介绍、比较与分析，提出现有制度的不足并从发展成熟国家的立法中借鉴经验，旨在得出通过提高市场准入制度的门槛来控制派遣市场的发展的结论。对劳务派遣单位的义务进行介绍与分析，提出细化立法的建议。而对派遣单位责任研究主要集中在对连带责任方面，现行立法规定连带责任对派遣单位带来的责任与风险过重，提出通过雇主责任重构与规定补充连带责任等方式来降低其责任与风险。
