城市商业银行经营转型的策略选择与风险防范

我国城市商业银行在贷款过度集中、组织架构效率下降、激励约束机制欠缺、收入结构单一的背景条件下进行经营转型,选择适当有效的策略显得尤其重要。笔者认为,城市商业银行通过隐性跨区经营、提高分支机构实用性、强化利益相关者管理以及多元化业务创新等策略,有望实现经营机制的优化。另外,在转型过程中,城市商业银行还要注意利益平衡、转型时机、人才储备、小企业不良贷款等方面的风险防范。     

国内外嵌入性研究述评

对现有国内外嵌入性研究进行了评述。指出:目前嵌入性的概念内涵已较为成熟;一些学者综合社会资本和社会网络研究,对嵌入型的概念构成提出了不同的维度划分方式,多数学者从不同侧面探讨了嵌入性与企业活动的关系;现有研究的不足主要体现为,不同层面的研究没有有效交融、嵌入性与企业活动间联系研究的系统性有待开发、一些社会网络研究方法等无法被充分应用于此方面的研究中。     

Shareholder Value Maximisation,Stock Market and New Technology: Should the US Corporate Model be the Universal Standard? 1

In 1992 a blue‐ribbon group of US economists led by Michael Porter concluded that the US stock market‐based corporate model was misallocating resources and jeopardising US competitiveness. The faster growth of US economy since then and the supposed US lead in the spread of information technology has brought new legitimacy to the stock market and the corporate model, which is being hailed as the universal standard. Two main conclusions of the analysis presented here are: (a) there is no warrant for revising the blue‐ribbon group’s conclusion; and (b) even US corporations let alone developing country ones would be better off not having stock market valuation as a corporate goal.     

我国政策性农业保险实施效果评价

根据在政策性农业保险试点地区进行实地调研所得的数据,对农户对我国政策性农业保险实施效果的评价结果进行了描述性统计分析。调研结果表明:不同地区的农户对农业保险的需求程度不同,因此其对农业保险实施效果的评价结果也不尽相同;总体来讲,农业保险在稳定农作物产量、稳定农户家庭收入、增强农业抵御风险能力等方面确实发挥了一定的作用,但还未具有明显的长期效果,并未得到广泛认可。     

中医综合疗法治疗小儿腹泻40例疗效观察

目的观察中药内服外用等综合治疗措施对小儿腹泻的临床疗效。方法 80例小儿腹泻病例纳入观察,以随机数字表法随机分为对照组和治疗组,各40例。所有患者均给予常规的基础治疗包括补液、纠正水电解质紊乱,对照组给予蒙脱石散,治疗组给予中医综合治疗措施,疗程均为5d。结果对照组止泻时间平均(3.32±0.53)d,治疗组止泻时间平均(2.36±0.38)d,经t检验,差异有统计学意义,P<0.05。治疗组显效16例,有效22例,无效2例;对照组显效11例,有效21例,无效8例,经Ridit分析,治疗组优于对照组,P<0.05。结论采用中药内服外敷、结合饮食调护的综合疗效治疗小儿腹泻疗效较好,值得推广使用。     

Is there Causal Relationship between Money Supply Growth and Inflation in China? Evidence from Quantity Theory of Money

This study examines the causal relationship between Chinese money supply growth and inflation, using the bootstrap Granger full‐sample causality test and sub‐sample rolling‐window estimation test to determine whether such a relationship in China supports the quantity theory of money. The result indicates that there is a unidirectional relationship from inflation to money supply growth. However, considering structural changes in two series, we find that short‐run relationships using full‐sample data are unstable, which suggests that full‐sample causality tests cannot be relied upon. Then, we use a time‐varying rolling‐window approach to revisit the dynamic causal relationship, and the results show that money supply growth has both positive and negative impacts on inflation in several sub‐periods, and in turn, inflation has the same effects on money supply growth for China. These findings are basically consistent with the modern quantity theory of money from the perspective of money supply and price level. When money supply growth does not outweigh output growth, inflation should not be curbed only by decreasing money supply. It notes that a stable money supply growth is critical to price level stability and economic development in China.     

供应链是价值链的一种表现形式

先介绍了企业关系的演变和发展 ,概述了供应链/价值链产生和发展的背景、供应链/价值链研究的发展。然后从哲学的角度深入分析供应链/价值链之间的关系和区别 ,首次得出“供应链是价值链的一种表现形式 ,两者是内容和形式的哲学关系”的结论。弄清两者的关系 ,对供应链/价值链的研究和应用有很大的现实指导意义。价值链管理应注重宏观、战略、定性等方面的研究和应用 ,而供应链管理则应更加注重微观操作、运行管理、定量等方面的研究和应用。     

能源错配对制造业碳排放效率的影响研究

能源要素作为考察资源配置效率不可或缺的因素,其配置是否有效与经济和环境的发展息息相关。为了判断我国制造业是否存在能源错配现象,厘清行业异质背景下能源错配影响碳排放效率的理论机制,基于2012—2017年制造业细分行业的面板数据,在测度行业能源错配指数基础上,构建计量模型实证检验能源错配对碳排放效率的影响。研究结果表明:(1)制造业各行业间存在不同程度的能源配置扭曲。(2)改善能源错配显著影响行业碳排放效率,但行业异质性使得影响的程度和方向有所不同。研究结论对宏观角度及时调整行业能源配置、加强环境保护约束,完善环境补偿机制、引导低碳创新技术研发具有重要政策启示。

HEALTH INSURANCE,FERTILITY, AND THE WANTEDNESS OF PREGNANCIES: EVIDENCE FROM MASSACHUSETTS

Health insurance reform in Massachusetts lowered the cost of both pregnancy (by increased coverage of pregnancy‐related medical events) and pregnancy prevention (by increasing access to reliable contraception). We empirically examine fertility responses and find no overall effect from increased coverage due to the Massachusetts reform. This finding, however, masks substantial heterogeneity. For married women aged 20 to 34—with high latent fertility and pregnancy wantedness—fertility increased by approximately 1%. For unmarried women in the same age range—for whom pregnancies are typically unwanted—fertility declined by 8%. (JEL I13, I18, J13)
