文章以开放系统理论为基础,讨论制造商采用多元化的渠道对两种不同形式的渠道冲突的作用,以及市场化水平对渠道多元化与跨渠道冲突、渠道内冲突之间关系的调节效应。从中国制造商一方收集520份调查数据,引入市场化指数二手数据,应用统计方法分析数据和检验假设。文章的数据检验结果发现:第一,制造商采用多元化的销售渠道会导致制造商内部各条渠道之间产生冲突,也会加剧制造商与同一条渠道内合作经销商之间的冲突;第二,制造商采用多元化渠道通过加剧与同一条渠道中经销商之间的渠道内冲突,进而降低企业绩效;第三,市场化水平会弱化渠道多元化对跨渠道冲突的正向影响。文章最后从理论贡献、实际应用和研究不足等方面对研究结果进行了讨论。

以任务技术匹配(TTF)模型为理论依据,将网络交互策略分为跨组织信息系统(IOS)助力的交互策略和社交媒介(SM)助力的交互策略,通过检验网络交互策略与跨组织治理方式(分为合同治理和关系型治理)之间的TTF匹配效应,探讨网络交互策略如何提高企业跨组织治理的效力问题。研究结果显示:IOS助力的交互策略与合同治理相匹配而与关系型治理不匹配,因此它有助于提高合同治理的效力,但对关系型治理的效力有弱化或不显著的影响作用;SM助力的交互策略与关系型治理相匹配而与合同治理不匹配,因此它有助于提高关系型治理的效力,但对合同治理的效力有弱化或不显著的影响作用。论文最后讨论了研究结果的理论和实践意义以及未来的研究方向。
