"Yunnan tea" has been included in"Ten Advantage Characteristic Industry of Yunnan" and it is an important way of shaking off poverty and becoming prosperous for the farmers. However, the defect in supply chain is restricting the development of "Yun-nan tea". At present, there are few researches focus on tea supply chain and all of them are qualitative research, and quantitative research have not been found. This paper studies "Yunnan tea" supply chain through modeling and simulating based on Petri net. The paper models and analyses quantitatively current supply chain as well as a reconfiguration supply chain at first. Then it makes a comparative study of performance and efficiency of the two supply chains. The results show that the reconfiguration supply chain is more advantageous than the other. Thus, the quite reliable theory evidence and data for the necessity of reconfiguring "Yunnan tea" supply chain is found. Finally, some advice for reconfiguring "Yunnan tea" supply chain in the future is listed. This study is not only the furtherance and innovation of theoretical study of tea supply chain, but also provides intellectual support for Yunnan to construct a strong green economy province and develop ecological industry of Yunnan Tea.%“云茶”已被列为云南“优势特色产业十优十强”之一，是广大茶农脱贫致富的重要途径。然而，供应链不畅已成为制约“云茶”发展的关键，目前茶供应链研究成果不多，且均为定性研究，尚未发现定量研究的文献报导。对此，文章引入Petri网方法，采用建模仿真对“云茶”供应链进行研究。首先，分别对现有和重构后的供应链作Petri网建模和定量分析。之后，对两个供应链从时间性能和各环节运作效率等方面进行定量分析和比较研究。结果表明，重构后的供应链更有优势，从而为“云茶”供应链重构的必要性找到了切实可靠的理论依据和数据支撑。最后，对未来“云茶”供应链重构提出了若干建议。该研究不仅推进了茶供应链理论研究的深入和创新，而且可为云南建设绿色经济强省、打造“云茶”生态产业提供智力支持。
