The construction industry could be developed as a pillar industry of the national economy

since it has a strong pulling role in economic growth.However

little definite empirical evidence supports this argument.Using co-integration and Granger causality tests and error-correction model with taking Sichuan for an example

this article studies both short-term and long-term effects of the construction industry on the economy growth.Empirical tests show that in the long term the economy maintained equilibrium relations with the construction industry.A growth in the construction industry will lead to the economic growth;however the pulling role of the construction industry on the economy is limited.A growth in the construction industry will not predict economic growth in the short run.Thus

for Sichuan case the government is unable to stimulate the economy by focusing on development of the construction industry in the short run.Instead

in order to promote long-term development of the national economy it could implement stable and healthy development policies for the construction industry.
