The effect of private intel igence leak with big data between competition and cooperation on the supply chain is studied,the mass customization oriented original col aborative supply chain model three models of private intel igence leak are developed. optimal price,optimal profit and competitive advantage of different competitors are classified and compared,three kinds of competition model of competition and competitive profit difference are compared. The results show that the privacy leak background with big data,enterprises will choose cooperation when information cost is high;enterprises will choose competition when the information acquisition cost is low and final y form single middle agent,predict the developing direction of the supply chain and provides a theoretical basis for the government formulate corresponding policies. A numerical result was given to verify the effectiveness of conclusions.%为了研究大数据背景下私有信息泄露对供应链成员企业竞合关系的影响，构建了面向大规模定制的原始合作供应链模型以及私有信息泄露后的三种竞争供应链模型。对三种竞争模型中竞争方进入供应链的条件、最优价格、最优利润进行了分析之后又对三种竞争模型中竞争方与被竞争方的利润差进行了横向比较。研究发现：在大数据私有信息泄露背景下，当情报获取成本较高时，供应链成员企业会选择合作；当情报获取成本较低时，供应链成员企业会选择竞争并最终形成单一中间代理的供应链成员企业结构，为政府预测供应链发展方向并制定相应的引导政策提供了理论依据。最后通过数值分析验证了相关结论的有效性。
