Abstract: After analyzing the basic attribute of freeway，the freeway benefit is divided into economic benefit and social benefit. From microeconomics angle，the function of supply curve and need curve is gained according to the traffic and economy characteristic.Then the freeway supplyneed equilibrium analysis is taken，the producing mechanism of economic benefit and social benefit of freeway is studied. The research will be benefit to objective evaluation of freeway benefit and scientific decision-making of freeway construction items.

Key words: freeway, economic benefit, social benefit, consumer surplus, producers urplus, external effort
