Analysis on Power Grid Investment Base on Cointegration Theory and VAR Model

Article Preview

Abstract:

Based on the statistical data of US from the year 1977 to 2006, this paper examines the long-run equilibrium relationship and short-term fluctuations among power grid investment, economy and electricity consumption by employing the recently developed VAR model and cointegration theory. The results show that the electricity consumption has a positive effect on power grid investment while GDP has a negative impact. The development of electric power grid investment can be divided into three stages. To achieve the coordinate development of electricity and economy, the electric power industrial should develop in advance and try to be a new pillar industry.
