“克强指数“(KQI)是工业用电量、铁路货运量、贷款发放量等指标的结合，是英国著名政经杂志《经济学人》创造的用于评估中国GDP增长量的指标。“克强指数”指标关系研究首先以指标平稳性检验为前提，然后进行协整检验和因果关系检验，最后建立指标之间均衡关系及误差修正模型。实例表明山东省铁路货运量与工业用电量存在单项的因果的关系，工业用电量与铁路货运量、贷款发放量之间存在长期协整关系，并且短期调整机制对误差起到绝对修正作用。研究实验环境R语言。

Keqiang index is the combination with industrial electricity consumption, freight transported by railway and loans , and is an evaluated indicator ctreated by the economist of Chinese GDP growth. First, Keqiang index research based on the stationary test , and then done the co_integration test and Granger causality test. At last, the results established the relation of indicators co-integration and error correction model. The examples showed that the freight transported by railway and industrial electricity consumption are one-way causal relationship, and three indicators existed long-term co-integration relationship, short-term adjustment mechanism was very important for the error correction . The experimental environment used R language.
