Public Policy Supply for Successful Practice of the Xin’anjiang River Ecological Compensation Mechanism

The ecological protection of the inter-provincial river basin of Xin’anjiang River takes the ecological compensation mechanism as the starting point and achieves good results.The success of the mechanism is best reflected in its innovation of public policy supply,which is not only a vivid practice of Xi Jinping’s ecological civilization thought in the new era,but also establishes a model for absorption,transformation and export of policy supply.The effective supply of public policies on ecological environment is the realistic choice for the construction of ecological civilization in the new era.

Creating Inclusive Global Value Chains under the BRI from the Perspective of Public Goods Supply and Demand

Supply and demand of public goods provide a brand-new theoretical framework for research on the creation of inclusive global value chains(GVCs)under the Belt and Road Initiative(BRI).The supply of international public goods is an important positive variable for creating global value chains under the BRI,in which China and other developing countries involved,as well as their small and medium-sized enterprises(SMEs),are microscopic entities.When the BRI’s supply of instrumental,institutional,and conceptual international public goods is in equilibrium with the demand of GVC entities for public goods,the BRI creates necessary conditions for the extension of GVCs.GVCs created under the BRI are of great value in promoting inclusiveness,fair income distribution,balanced regional development,and the restructuring of international economic governance.Under the current GVC system,some developed countries have been wary about the BRI and even developed misgivings and biases.Nevertheless,developed countries may play an active role in bridging gaps in the BRI’s development and complement their respective strengths with developing countries for win-win cooperation.

The Equalization Gap of Basic Public Services Supply in China:An Empirical Study on Education,Health Care and Social Security

The equalization of basic public services which helps to meet people’s ever-growing needs for a better life is an important component of the supply-side structural reform under the new normal.This paper constructs the mechanism model and index of basic public services equalization,measures the equalization of education,health care and social security in China during the period of 2005-2016,and empirically tests the contributory factors with regional panel data.It is found that the equalization of basic public services has not been significantly improved by the last 12 years of urbanization;people tend to seek high-end consumption beyond basic public services with the increasing per capita disposable income;while the population structure and the gap between urban and rural areas constitute the main impediments,local governments’revenues and fiscal efficiency can significantly improve the equalization of basic public services.Therefore,the key to the supply-side structural reform of public services lies in enhancing the matching capability of public services in urbanization,reducing the consumption gap between urban and rural public services,and improving the efficiency of government’s public services expenditure.

A new focus on risk reduction: an ad hoc decision support system for humanitarian relief logistics

Particularly in the early phases of a disaster,logistical decisions are needed to be made quickly and under high pressure for the decision-makers,knowing that their decisions may have direct consequences on the affected society and all future decisions.Proactive risk reduction may be helpful in providing decision-makers with optimal strategies in advance.However,disasters are characterized by severe uncertainty and complexity,limited knowledge about the causes of the disaster,and continuous change of the situation in unpredicted ways.Following these assumptions,we believe that adequate proactive risk reduction measures are not practical.We propose strengthening the focus on ad hoc decision support to capture information in almost real time and to process information efficiently to reveal uncertainties that had not been previously predicted.Therefore,we present an ad hoc decision support system that uses scenario techniques to capture uncertainty by future developments of a situation and an optimization model to compute promising decision options.By combining these aspects in a dynamic manner and integrating new information continuously,it can be ensured that a decision is always based on the best currently available and processed information.And finally,to identify a robust decision option that is provided as a decision recommendation to the decision-makers,methods of multi-attribute decision making(MADM)are applied.Our approach is illustrated for a facility location decision problem arising in humanitarian relief logistics where the objective is to identify robust locations for tent hospitals to serve injured people in the immediate aftermath of the Haiti Earthquake 2010.

Quantifying and managing regional greenhouse gas emissions: Waste sector of Daejeon, Korea

A credible accounting of national and regional inventories for the greenhouse gas （GHG） reduction has emerged as one of the most significant current discussions. This article assessed the regional GHG emissions by three categories of the waste sector in Daejeon Metropolitan City （DMC）, Korea, examined the potential for DMC to reduce GHG emission, and discussed the methodology modified from Intergovernmental Panel on Climate Change and Korea national guidelines. During the last five years, DMC＇s overall GHG emissions were 239 thousand tons C02 eq./year from eleven public environmental infrastructure facilities, with a population of 1.52 million. Of the three categories, solid waste treatment/disposal contributes 68%, whilst wastewater treatment and others contribute 22% and 10% respectively. Among GHG unit emissions per ton of waste treatment, the biggest contributor was waste incineration of 694 kg CO2 eq./ton, followed by waste disposal of 483 kg CO2 eq./ton, biological treatment of solid waste of 209 kg CO2 eq./ton, wastewater treatment of 0.241 kg CO2 eq./m3, and public water supplies of 0.067 kg CO2 eq./m3. Furthermore, it is suggested that the potential in reducing GHG emissions from landfill process can be as high as 47.5% by increasing landfill gas recovery up to 50%. Therefore, it is apparent that reduction strategies for the main contributors of GHG emissions should take precedence over minor contributors and lead to the best practice for managing GHGs abatement.
