Granger causality tests show that 量误差修正模型；脉冲响应 there are unidirectional Granger causalities between electricity consumption and the explanatory variables. The error 0 引言 correction term of the vector error correction model (VECM) is 许多学者用不同的方法对电力需求预测进行 significant, and its coefficient has the expected negative sign, [1] [2] 了研究，如偏最小二乘回归 、分形理论 等。20 which implies that it indeed reflects an error correction
