Thinking of the Sound Development of the Third Party Logistics Based on the Exchange Theory

Based on the exchange theory,the article studies the contract curve formed by the cooperation between the manufacturing and the third party logistics,and puts forward the reason why both sides are reluctant to change.It is the indifference curves behind the Pareto efficient allocation point that causes the effect.And with the help of the first and second theorem of welfare economics,the article analyzes deeply the position in the market of the third party logistics and puts forward the views how the governments provides policies to protect the development of the third party logistics,how the governments set the time limit of policies support to encourage the growth of the third party logistic,and how both the manufacturing and the third party logistics strengthen their mutual learning curve effect.
