Based on water pollution data from the state-controlled monitoring sites and the manually compiled data on the evolution of the river chief system(Hezhangzhi 河长制), we used the Difference in Differences(DID) technique to identify the policy effects of the system in local practice. Our findings show that the system has achieved preliminary management of water pollution but has not significantly reduced the main water pollutants. This may indicate that local governments have whitewashed the symptoms rather than addressing the root cause. In the course of comprehensively advancing the river chief system, better governance results will be achieved if all levels of government formulate clear and appropriate goals, design sound and feasible accountability mechanisms, and invite professional third-party agencies specializing in water quality testing to supervise the work.展开更多

The superimposed effect of an aging population and low birthrate leading to a reduction in the labor supply would have a fundamental influence on the long term balanced development of China's population, implying that China's population policy must be adjusted. This paper argues that a gradual relaxation of the family-planning policy adjustments accords with the original intention of the population policy design and development direction. The universal second-child policy is the logical results of the adjustment and improvement of China's family-planning policy, and is designed to bring about positive effects on future demographic and economic development, particularly in sustaining the long term balanced development of China's population, easing the marriage squeeze, extending the demographic dividend, and delaying the population aging process. China needs to develop and improve support and governance systems for fully implementing the universal second-child policy, realizing the policy transition from rewarding one-child families to population security and the modern transition of governance systems and capacity to a universal second-child policy.展开更多

We chose Hebei province as a case to study, utilized standard methods from WHO/HAl and built interrupted time series （ITS） model to qualitatively and quantitatively evaluate the effects of NEMP in Hebei province from the utilization of essential medicines. Shortly after implementing EMP, the purchasing and utilization rate of essential medicines significantly increased, but no further continuous effects. In order to perfect the essential medicine policy, training of rational drug utilization should be strengthened, hierarchical essential medicine list and dynamic monitoring on the effect of NEMP are necessary.展开更多

Discussions are ongoing on how to measure the effectiveness of policy implementation at the local level. But there is no definitive theory of effective policy implementation, and very few frameworks have been found acceptable as the basis of an analysis of the effectiveness of policy implementation, especially on droughts. Based on the 2009–2010 extreme drought in Yunnan, China, this article presents a modified framework to assess the effectiveness of policy implementation by defining policy, practice, and performance, as well as a feedback loop by which to share the lessons learned. Water conservancy projects in Luliang County and the agricultural diversity program in Longyang County in Yunnan Province were analyzed from a farmers' perspective. It was found that farmers are highly dependent on government policies and projects, and the effectiveness of policies is measured by short-term, immediate, and tangible benefits rather than long-term adaptation strategies. The results highlight the urgent need to reduce risks by developing better awareness about climate change and drought and its impacts, increased understanding of drought hazards, and implementation of appropriate measures for long-term adaptation.展开更多

IntroductionSince economic reform and an opening-up in 1978, the Chinese government has decentralized its state-owned enterprises (SOEs) system in the centrally planned economy. The separation of government administration and enterprise management is moving China toward a market-oriented economy, forcing Chinese enterprises to become more competitive and more efficient. Market forces of supply and demand are intended to govern firms’ industrial production, which is no longer subject to government planning and control.展开更多

文摘The 13 th Five-Year Plan(2016─2020), with the balanced development of population being the core element, is crucial for China. The superimposed effect of an aging population and low birthrate leading to a reduction in the labor supply would have a fundamental influence on the long term balanced development of China's population, implying that China's population policy must be adjusted.
