Abstract: This paper analyzes the nature of Chinas taxsharing system from the perspective of contract and explains the positive and negative effect of this system by unified framework. The taxsharing system is a flexible revenuesharing contract system, because it is a combination of a series of specific contracts on residual distribution among central government and local governments. These specific contracts can be classified as four kindsfixed wage contracts, fixed price contracts, decentralized contracts, and revenuesharing contracts, which are complementary and form a flexible incentive system. Under asymmetric information the incentive system strengthens local governments motivation on economic growth, but it will distort the local governments behavior, lead to repeat construction and extensive economic growth model.
