Abstract

The purpose of this study is to analyze the causality of electricity consumption and econmic growth and draw policy implications. To do this, we used Testing Prodedures of Unit Root and Cointegration and then VECM and Granger causality test using data taken from China over the period 1971 to 2008. As results, there are long and short term causalities between electricity consumption and economic growth of China. These results provide a few implications to policy analysts in China. First it is still available that the electricity comes before the economic development. The increase of electricity consumption promotes economic growth. Of course there are other factors to the economic growth, but the stable supply of electricity is necessary. Second, this paper confirms the assertion that the increase of GDP expands electric consumption is valid.

본 연구의 목적은 중국의 전력소비와 경제성장의 인과관계를 분석하고 그 방향을 확인하여 정책적 시사점을 도출하는 것이다. 이러한 목적을 달성하기위해 1971년~2008년 동안의 연간자료를 사용하여 단위근 검정, 공적분 검정, 오차수정모형을 통한 Granger-인과검정을 하였다. 검정결과 중국의 전력소비와 경제 성장사이에는 장, 단기적 양방향 인과성이 발견되었다. 이러한 결과는 중국의 정책분석가에게 몇 가지 유용한 시사점을 제공한다. 첫째: "경제가 발전하려면 전력이 선행해야 한다."라는 중국의 발전전략이 지금도 유효하다. 즉 전력소비의 증가는 경제성장을 촉진한다. 물론 경제성장에 미치는 다른 요인들이 존재하고 전력은 그 일부분이지만 경제성장을 하기위해서는 안정적인 전력공급이 필요하다. 둘째: 본 연구는 실질 GDP의 증가가 전력소비를 늘린다는 주장도 성립함을 확인하였다. 이는 직관적으로 소득이 늘어나면 보다 많은 전력을 필요로 하는 제품사용이나 수요가 증가할 것이다.
