中文摘要：

【目的】寻找企业供应链合作伙伴关系中的问题以及影响供应链合作绩效的因素。【方法】本文通过对吉林省玉米供应链合作伙伴玉米加工龙头企业（县级以上）、物流企业和农户的调查,构建结构方程模型,运用AMOS17.0运算分析玉米供应链合作伙伴关系对玉米供应链合作绩效的影响。【结果】供应链成员间的协作能力对供应链合作绩效的影响较大,综合影响达到0.825,而成员间的合作意愿对合作绩效的影响相对较小,但对合作绩效的直接影响较强。【结论】企业内外部环境的不确定性不利于成员间合作的建立,供应链成员之间的合作意愿与协作能力对整个供应链合作绩效有正的影响,且协作能力的影响更大;玉米供应链合作伙伴关系强度不直接影响供应链合作绩效。
