全球生产网络构建下的中国民营跨国公司成长机制
全球生产网络 民营跨国公司 成长机制 吉利集团
2018/6/21
在企业构建全球生产网络的格局下,企业资源、网络构建与企业成长之间存在协同演化机制,作为影响我国民营跨国公司成长的内外因子,构建全球生产网络为企业获取全球资源提供了路径,而企业构建全球生产网络的动机和机会受企业拥有的内部资源的影响,这两个子系统通过彼此影响和相互作用,进而对跨国公司成长产生协同促进效应。两者协同程度越高,就越能够促进跨国公司的成长。
基于节点态度的社交网络信息传播模型
社交网络 信息传播模型 SIRS 节点态度
2018/6/13
了揭示信息在社交网络中传播的内在规律,对社交网络的信息传播过程进行深入的研究,社交网络的信息传播过程除了受信息本身的吸引力和社交环境的影响,同时受节点对消息的态度的影响。然而,现有信息传播模型对节点态度考虑不足,不能体现节点态度的差异对信息传播所产生影响。
信号控制交叉口机动车绿灯间隔—安全可靠度曲线簇
交通工程 绿灯间隔 可靠性理论 安全可靠度 Monte Carlo模拟 曲线簇
2018/11/16
为了提高信号控制交叉口(以下简称为“交叉口”)的安全性,提出一种基于安全可靠度的交叉口机动车绿灯间隔计算方法,并绘制面向工程应用的绿灯间隔—安全可靠度曲线簇. 首先,对经典的交叉口绿灯间隔计算方法进行了归纳;其次,推导出基于安全可靠度的绿灯间隔计算方法公式并对各影响因素进行敏感性分析;再次,基于Monte Carlo算法模拟反应时间与车辆减速度的交互过程,对模型进行求解;最后,根据模拟结果,绘制了...
P2P校园贷款个人违约风险因素指标探析
P2P校园贷款 金融数据挖掘技术 Adaboost算法 校园贷风险管理
2018/5/9
基于美国Lending Club网贷平台,通过探究P2P校园网络贷款真实数据,运用数据挖掘Adaboost算法识别借款人违约风险重要因素指标。结果显示:除借款利率外,社会信用、社会关系资本和还款行为都是影响借款违约风险的重要指标。在此基础上,提出了校园贷款家校知情、社会信用信息共享、加强大学生信用意识培养等降低校园贷款个人违约风险的建议,以期减少校园贷款借款人违约风险。
北京地区大气温度及重力波活动的季节变化
激光雷达 大气温度 重力波 势能密度
2018/5/4
利用瑞利激光雷达观测数据,分析了北京地区35~70km高度范围内大气温度和重力波活动的季节变化.发现北京地区30~70km高度范围内的大气温度有明显的年周期变化:平流层顶最高温度出现在6,7月份,大约为270K;中间层70km高度最低温度也出现在6,7月份,大约为200K.以2014年10月14日晚数据为例,分析重力波势能密度,发现50km以下重力波势能存在耗散,而在50km以上重力波近乎无耗散地...
