任务指令: 你需要根据以下这个金融逻辑, 组合创新 alpha
数字化客户粘性溢价
假设
在数字经济时代，拥有高度数字化客户互动渠道和强大用户粘性的公司（如高频使用的移动应用、高活跃度的在线社区、高转化率的私域流量），能够以更低的边际成本获取更高质量的用户数据和现金流。这种数字化粘性构筑了强大的竞争护城河，其价值尚未被传统财务指标充分定价，有望在未来产生持续的超额收益。
实施方案
整合月活跃用户(MAU)增长率、用户日均使用时长、用户生命周期价值(LTV)与获客成本(CAC)的比率等数字化运营数据字段。使用时序动量算子（如ts_rank）对过去一年内“用户时长增长率”与“LTV/CAC比率”的综合得分进行排序。对排名持续提升且处于前30%的公司赋予正向阿尔法权重，并结合横截面标准化确保信号在同类商业模式公司（如消费互联网、金融科技）内进行比较。
阿尔法因子优化建议
数字化粘性的价值在不同增长阶段（导入期、成长期、成熟期）差异显著。建议引入“增长阶段分档”算子，根据用户规模增速和营收增速对公司进行动态分类，在各自的阶段组内计算粘性指标的相对强弱，以避免对处于不同生命周期公司的误判。此外，可叠加“变现效率变化”指标（如每用户平均收入(ARPU)的环比加速度），在粘性提升的同时，筛选出变现能力同步增强的标的，以增强信号的纯度。
