+供应链集中度风险溢价
+假设
+当企业对少数供应商高度依赖时，其运营韧性较弱，易受外部冲击（如地缘政治、自然灾害或供应商财务危机）影响，从而增加盈利波动性和违约风险。市场通常低估此类“隐性脆弱性”，导致高供应链集中度公司的股票在中期内表现落后。因此，可对供应链集中度高的公司建立空头仓位，反之建立多头仓位。
+实施方案
+使用供应商集中度相关指标（如前五大供应商采购占比）衡量依赖程度。为提升数据覆盖，采用时序回填算子处理缺失值，并将该指标与行业分位数比较以控制结构性差异。同时结合应付账款周转天数和采购成本波动率作为辅助验证变量，增强信号稳健性。

-供应链集中度风险溢价
+供应链议价能力不对称因子
 假设
-当企业对少数供应商高度依赖时，其运营韧性较弱，易受外部冲击（如地缘政治、自然灾害或供应商财务危机）影响，从而增加盈利波动性和违约风险。市场通常低估此类“隐性脆弱性”，导致高供应链集中度公司的股票在中期内表现落后。因此，可对供应链集中度高的公司建立空头仓位，反之建立多头仓位。
+在供应链关系中，若企业对少数客户或供应商存在高度依赖，其议价能力将显著弱化，导致成本转嫁能力受限或收入稳定性下降，从而承担额外的经营风险。市场往往低估此类结构性脆弱性，使得高依赖度企业被系统性高估（即未来收益偏低），而低依赖度、议价能力强的企业则被低估（即未来收益偏高）。因此，做空高集中度企业、做多低集中度企业可捕获由此产生的风险溢价。
 实施方案
-使用供应商集中度相关指标（如前五大供应商采购占比）衡量依赖程度。为提升数据覆盖，采用时序回填算子处理缺失值，并将该指标与行业分位数比较以控制结构性差异。同时结合应付账款周转天数和采购成本波动率作为辅助验证变量，增强信号稳健性。
+核心指标为企业前五大客户销售额占比与前五大供应商采购额占比之和，用于衡量整体供应链集中度；该指标需进行行业中性化处理以剔除行业固有结构差异，并通过横截面标准化生成Z-score因子值。对于缺失值，采用过去12个月滚动窗口的时序填充策略（如可用历史均值）；同时引入应付账款周转天数和销售毛利率作为辅助验证变量，以确认议价能力传导机制的有效性——预期高集中度企业应具有更长的应付账款周期（议价弱致付款快）和更低的毛利率（成本无法转嫁）。
