China has continuously stepped up its efforts to protect the ecological environment of the Ganjiang River Basin. The government has played a leading role, but the residents, who have also played an important role in this issue, are often overlooked. Consequently, it is necessary and urgent to study the willingness of the residents, who are the direct stakeholders, to pay for the protection of the ecological environment of the Ganjiang River Basin. Based on a survey of 773 households, this study examines the downstream residents' willingness to pay (WTP) and their payout levels. Using the payment card (PC) contingent valuation method (CVM), we measure the payment probability of the downstream residents and the amount they are willing to pay. Additionally, Heckman's two-stage model is adopted for exploring the influencing factors of the surveyed residents' WTP and payout levels and avoiding the possible presence of sample selection bias. The results showed that 75.03% of the surveyed residents are willing to pay for ecological compensation in the Ganjiang River Basin. The downstream residents are willing to pay an annual average amount of about $47.62/household for ecological compensation. The factors that significantly influence their WTP include the educational background, work type, residential location, and water quality and quantity. In the case of payout levels, the influencing factors include the education background, work type, household annual disposable income, and water quality and quantity. In addition, the factor of value recognition is marginal and significantly related to WTP and payout levels. The results of this empirical study have important policy implications and recommendations that the government should intensify its propaganda about the ecological value, increase investment in education, and establish a variety of ecological compensation payments, in order to protect and improve the ecological environment of the Ganjiang River Basin.

Abstract:In 2015, a new round reform of the marketization for the electricity sales in China is launched. This paper investigates the policy selection for this reform in China, from the perspective of political economics. We analyze the policy selection of the 2015 reform from two aspects of market structure and pricing mechanism. According to the policy of the 2015 reform, China's power industry is of great potential to develop the market structures of "integration of generation and retail services while integrating transmission and distribution" versus "integration of generation, distribution and retail services while independent of transmission". Those two market structures have advantages on competition efficiency and political practicability. For the pricing mechanisms, the power exchange market of China can take bilateral contracts for the long-term trading and double-sided auctions for the short-term trading, as well as for the spot market. In addition, electricity financial market can be set up as a supplement for the power exchange market, which is of potential contribution to manage the risk and discover the effective price. The 2015, reform assigns two state-owned grid companies the responsibility of the demand side management. The intelligent system to improve the information management of energy consumption can be established. Utilization of renewable energy is also emphasized in the 2015 reform for energy sustainability in China. Effective policy instruments, such as the efficient subsidy policy, an independent exchange market, and a quota system, for the promotion of renewable energy utilization, can be implemented.

This article tries to analysis water balance and solve the current problem In yulin city as an exampleunder the background of urbanization. Firstly, urbanization is a complex dynamic process, which contains many factors. Analysis the development process and its development and utilization of water resources conditions. Secondly, based on the basic characteristics of water resources of the city under the background of urbanization, further explores the causes for the effective use of water resources situation is not optimistic and analysis of supply and demand balance of water resources. Finally, finds the reason of yulin city belongs to the shortage of water resources, and limited carrying capacity. And puts forward practical measures to ease the urbanization that brings the contradiction of water resources supply and demand. It will fundamentally solve the issue of water resource shortage, balance of water resources supply and demand of local district.
