Since it lacks theoretical and technological solutions for guiding the eco-transformation of 1st and 2nd generation of development estates (industrial parks) and construction of eco-industrial parks (EIP), the principles for construction and optimization of EIP were put forward through the analyzing of the function and structure of industrial eco-system in EIPs. The 3rd Party Reverse Logistic System (3PRLS) was then introduced to improve the efficiency of materials recycling rate in the operation of EIP. The operation and profit model of 3PRLS were provided, and its information platform was designed for accomplishing the former functions by applying the knowledge of expert system, network topology, and data base. This research introduced the “decomposer” – the 3PRLS to traditional linear industrial system, which is satisfied with market condition as well as technologically feasibility. The technical solution for 3PRLS was also provided.
