In this paper, we calculate the coal efficient utilization ratio (CEUR) of 29 regions in China from 1995 to 2006, by applying data envelopment analysis (DEA) based on the regional own production frontier. And three inputs (labor, capital stock and coal utilization amount) and one output (GDP) are chosen for DEA. Results show that, the more developed area is, the higher CEUR is. The eastern, central...
Solid waste abatement is attracting wide attention, with its generation increasing rapidly in China. In this paper, we calculate the solid waste rational abatement ratio (SRAR) of 30 regions in China from 1995 to 2006, by applying data envelopment analysis based on the regional own production frontier. Results show that, the more developed area is, the lower SRAR is. The eastern, central and western...
This paper estimates the health loss due to PM10 via the impacts pathway approach used for ExternE Project in the counties in Central China in 2006. The estimation results show that the external costs were 55.38 billion Yuan, amounting for 2.26 percent of GDP in Central China in 2006. The health loss contributed to the air pollutants have exceeded the meaning of economic costs, also implicated the...
Based on the game theory, this paper formulates the concession agreement as an incomplete contract model to investigate the effects of different ownership structures on the efficiency of Build-Operate-Transfer (BOT) project. If the ownership is attributed to the private sector, it has stronger incentive to engage in cost reduction investment. However, the moral hazard arises from the incompleteness...
This paper examines the possibility of contractual breach in BOT projects. The main advantage of BOT Scheme is that payoff externality can be internalized through bundling construction and management operations. However, the efficiency of BOT contract is flawed if private company with limited liability intentionally cancels the concession contract. The paper also investigates the deposit policy to...
This paper formulates the BOT concession agreement as an incomplete contract model to analyze the inefficient problems arising from the collusion between government inspector and project company. The main advantage of BOT project is that the cost externalities could be internalized in the form of consigning both construction and operation to the project company. However, the moral hazard is caused...
