　　The European Union released the 2002/95/EC RoHS and 2002/96/EC WEEE directives in February of 2003. RoHS restricts new electrical & electric equipment that is placed on the EU market from containing lead, mercury, cadmium, hexavalent chromium, poly-brominated biphenyls, or polybrominated diphenyl ethers starting July 1, 2006. The purpose of WEEE is to reduce electrical& electric equipment waste disposal through the reuse, recycling, and other forms of. Therefore, The European Union RoHS/WEEE to influence the computer industry also is quite significant. This research construct the cost function to analyze the change of cost when computer industry introducing the green supply chain, calculating producer surplus difference which has or does not have the green supply chain. In this situation, it’s helpful to appraise computer industry benefit. Also, the social exterior cost brings into line with the consideration to calculate their relation. Furthermore, the relation between green supply chain and collaborative transportation management were also developed.

 　　A case study with a computer industry and other relevant data was provided to illustrate the results. These models are shown to be the cost function effectiveness of computer industry more than Ordnance Bench Mark, Original Equipment. In economics of scale, some of samples prossess the decrease return to scale, but most samples prossess the increasing return to scale. In economics of scope, all of samples prossess the economics of scope. In the green supply chain, this study adopts the computer industry in green market of cost data to calculating difference of producer surplus which has or does not have the green supply chain. According to the cost of Europe market in 2006, the difference of producer surplus with computer industry is 1.06,768 million ten thousand Yuan. In social exterior cost, the air pollution cost, the waste water pollution cost and the reject pollution cost were also considered, the social exterior cost with computer industry is 3.32,785 million ten thousand Yuan. Finally, the results indicate that computer industry can save 1.7% to 3.2% costs under collaborative transportation management. The above all results besides may supply various industries to do for the reference, also may provide the government assists.
