规制分权化对电力行业发展的影响:基于中国省级面板数据的经验研究

本文主要讨论了中国当前规制分权化背景下的地方规制机构与被规制企业之间的合谋问题,而合谋会导致规制低效率。基于面板数据,利用固定效应估计法对1998～2003年规制分权化的效果进行经验研究,结果表明规制分权化没有产生正面效应。因此,本文认为解决问题的关键是机制设计。     

现代烟草循环农业园区运行模式探索

随着烟草业生产方式转变,适应生态保护的要求,传统烟区纷纷尝试建设现代烟草循环农业园区.在运行模式上,目前主要有“烟草公司+农户”、“有限责任公司+农户”和“合作社+农户”模式,但这三种模式未能较好的兼顾各方利益.“政府引导、企业主导、合作社经营、农户参与、科研机构支持”的“五位一体”运行模式或能很好地推动园区现代烟草循环农业的发展,达到提升烟叶品质、改善生态环境和促进烟农增收的目标.     

黄河下游沿黄地市农业高质量发展水平评价及比较研究

[目的]为科学测度黄河流域特定区域农业高质量发展水平。[方法]文章以黄河下游河南、山东两省及其17个地市为研究对象,基于省级和市级数据,依据农业高质量发展的理念、内涵、思想与要求,从农业生产高效益、农业产品高质量、农村居民高收入、资源利用高效率、环境质量高水平5个准则层出发构建黄河下游沿黄地市农业高质量发展评价指标体系。运用熵权TOPSIS模型得出测度值,对下游省、市两级发展水平进行对比分析;再结合聚类分析法把相对优、劣势相同的地市分类,明确各类地市未来发展重心;最后通过各地市空间分布状况直观地观测各地市间的差异。[结果]（1）黄河下游地区农业高质量发展总体水平山东省略高于河南省。（2）下游沿黄17个地市中济南农业高质量发展水平最高,新乡农业高质量发展水平最低。（3）根据相对优、劣势把17个地市划分为6类。[结论]沿黄地市农业高质量发展各有其短板和优势,市级间农业高质量发展水平差异较大,提升重点是因地制宜、扬长避短,充分发挥各自优势,着力补齐发展短板,以实现黄河下游地市农业高质量协调发展。     

Time-consistent mean-variance reinsurance-investment strategy for insurers under CEV model

We consider an optimal time-consistent reinsurance-investment strategy selection problem for an insurer whose surplus is governed by a compound Poisson risk model. In our model, the insurer transfers part of the risk due to insurance claims via a proportional reinsurance and invests the surplus in a simplified financial market consisting of a risk-free asset and a risky stock. The dynamics of the risky stock is governed by a constant elasticity of variance model to incorporate conditional heteroscedasticity as well as the feedback effect of an asset’s price on its volatility. The objective of the insurer is to choose an optimal time-consistent reinsurance-investment strategy so as to maximize the expected terminal surplus while minimizing the variance of the terminal surplus. We investigate the problem using the Hamilton-Jacobi-Bellman dynamic programming approach. Closed-form solutions for the optimal reinsurance-investment strategies and the corresponding value functions are obtained in both the compound Poisson risk model and its diffusion approximation. Numerical examples are also provided to illustrate how the optimal reinsurance-investment strategy changes when some model parameters vary.     

China's Financial Fragility and Policy Responses

This article discusses the problems facing China in the wake of the Asian financial crisis. Chinas has so far (September 1998) avoided devaluation of its currency, but growth has slowed down and much more economic reform is needed, especially of the fragile banking system. The article focuses on China's financial fragility and outlines the required policy measures.

Completing China's Interest Rate Liberalization

China's recent removal of the last ceiling restriction on deposit rates in October 2015 is a milestone in interest rate liberalization, but not the end of it. International experience suggests that, without structural and quantitative reforms, simply freeing interest rates can result in major financial stress. Before China's central bank can completely relinquish implicit or explicit guidance for commercial banks' interest rate determination, it needs to accomplish two tasks: improvement of commercial banks' pricing capability as well as the monetary policy transmission mechanism. Both tasks require significant reform measures to be initiated, such as enforcing market discipline, forming a new monetary policy framework, developing money and capital markets, abandoning quantitative restrictions on credit and reforming the financial regulatory system.     

应用心电向量图诊断心房肥大、心室肥厚的体会

探讨心电向量图诊断心房肥大、心室肥厚的临床价值。应用心电工作站对收集的病例进行观察检测。对比心电图和心电向量图诊断心房肥大、心室肥厚的敏感性、特异性、准确性。结果为心电向量图对心房肥大、心室肥厚诊断的敏感性及准确性较心电图高，且具有一定的特异性。心电向量图在心房肥大、心室肥厚的诊断中可弥补心电图的不足，是值得推广应用的。     

Influence of Casino Impact Perception on Sense of Place: A Study on Casino-Liberalized Macao,China

Although the casino impact perception (CIP) of residents may influence their sense of place (SOP) and therefore the prosperity of casino destinations, little research has been conducted on such influence. The present study aimed to close the knowledge gap by investigating the presence of such influence in Macao, an important casino place in China and a leading casino center in the world. A structured questionnaire survey was administered to 500 Macao residents. The following results were obtained: (1) both SOP and its sub-dimensions were affected by CIP factors, (2) positive CIP factors had a stronger influence on SOP than did the negative ones, and (3) CIP factors were more important than the five socio-demographics (i.e. age, marital status, income, education, and occupation) as controlled variables in predicting SOP. This study contributes to the knowledge of the influence of CIP on SOP and provides useful policy implications for casino place management.
