摘要：勞務派遣單位是勞務派遣中的核心角色，其法律制度的完善有利于發揚勞務派遣的優勢與價值。具體來看，勞務派遣單位的市場準入制度、義務和責任三個方面分別從成立前、運營中和造成損害后對派遣單位起到制約作用，對派遣單位發展的規范性十分重要。文中對勞務派遣單位的市場準入制度做了介紹、比較與分析，提出現有制度的不足并從發展成熟國家的立法中借鑒經驗，旨在得出通過提高市場準入制度的門檻來控制派遣市場的發展的結論。對勞務派遣單位的義務進行介紹與分析，提出細化立法的建議。而對派遣單位責任研究主要集中在對連帶責任方面，現行立法規定連帶責任對派遣單位帶來的責任與風險過重，提出通過雇主責任重構與規定補充連帶責任等方式來降低其責任與風險。
