运用双边市场理论,以委托—代理理论为分析框架,分析了淘宝在线交易平台企业解决信任问题的机制:平台企业提供的市场竞争机制降低了代理人的道德风险行为;平台企业运用权威治理机制监控委托人和代理人的行为并作出奖惩;平台企业还设计了相应的担保制度,防范委托人可能的机会主义行为。淘宝的案例不仅为解决网络社区的信任问题提供了范例,也对"韦伯命题"作出了回答。

The electrosynthesis of value-added fuels and chemicals from carbon dioxide reduction reaction(CO_(2)RR)is a promising approach for realizing the objectives of carbon neutrality[1].Nevertheless,the current production of desirable multicarbon(C_(2+))chemicals,such as ethylene(C_(2)H_(4)),still encounters challenges related to low selectivity,low current density,and the requirement for high-purity feeding gas[2].

在网络数据管理优化问题的研究中,对等P2P为点对点网络通信。由于数据特征受到主观因素的影响较大,无法形成固定的关联特征,使得关键特征定位往往需要进行较大规模的大数据对比,传统的关联规则方法应用到此网络特征搜索过程时,建立的规则往往较为混乱甚至无规则可言,造成数据特征挖掘耗时,无效挖掘行为较多,效率较低。为此,提出利用Apriori算法的对等P2P网络中大数据关键特征挖掘方法。筛选对等p2p网络中大数据特征,选取聚类中心,并针对聚类中心进行关联性计算,删除关联性较差的特征。根据Apriori算法相关理论,对数据进行连接和剪枝处理,建立大数据关键特征挖掘模型。实验结果表明,利用改进算法进行对等p2p网络中大数据关键特征挖掘,能够提高挖掘的准确性,满足p2p网络的实际需求。
