The Mative Force for Drawing up the Land Use Overall Planand Its Validity Term and Characteristic

Li Boheng

Strategic Study of CAE 2007, Volume 9, Issue 3,   Pages 1-5

Abstract:

Drawing up the overall plan for land use is the guarantee to provide land use for the construction of a well-off society, and is an important measure to strengthen the macroeconomic regulation. The paper describes the three motive forces from the theoretical point of view for promoting this plan:safety in grain production, stable development of economy, and environmental protection. In order to better serve the economic development, the author proposed to divide the overall plan into three phases based on the economic development need:The first is a strategic plan——medium and long term land use plan;the second is a campaign plan——five-year land use plan in concordance with the State's Five-year Plan;the third is a tactic plan——the detailed regional land use plan which is characterized by goal unity, total quantity invariability and dynamical demand. In order to establish a persistent effect mechanism for land use and to prohibit the unjustified appropriation of farmland, the author proposes:The National People's Congress should draw up"the law of land use planning" and"the law of basic farmland protection" ;The tracking of the basic farmland usage using the remote-sensing technology should be established;Land use should be dynamically supervised; Farmland use contract should be signed with farmars.

Incentive and Validity of Compensation Contract for PPP ProjectDepending on Concession Income

Wu Xiaoling,Zhou Jing,Wang Jining,Peng Yichen

Strategic Study of CAE 2014, Volume 16, Issue 10,   Pages 77-83

Abstract:

In consideration of the uncertainty of PPP project benefit, firstly a relative index to describe the operating compensation for the project is introduced to design a single period compensation contract based on the government’s need. Then based on the fact that the private investment variable can’t be included in the contract, a game model between the public and private sector is proposed to explore the contact’s optimal form, incentive effect and valid condition respectively from the centralized and disperse decision-making. The research results show that the obtained optimal contract can encourage the private investor to choose the same optimal investment scale as the government’s centralized decision-making, and share both risks and revenues with the government. However, the valid compensation must satisfy the project’s social welfare constraint, which implies the valid compensation should be adapted to different actual scenes for PPP project.
