基于解释结构模型的应急物流影响因素研究

尽管起步较晚,但近几年对应急物流的研究呈现出良好地发展态势.文章从政府与物流企业的角度选取了七个应急物流的关键影响因素,并利用解释结构模型对七因素进行了层次化处理.研究发现应急物流组织机制是最深层的影响因素,应急物流资全、物资的筹措起承上启下的作用,是应急物流的有力保证,技术研发、中心构建、人员管理是应急物流的中层影响因素,而物资储备、运输与配送是应急物流的表层因素,对应急物流产生直接影响.     

农村人力资本积累的区域差异及其影响因素研究

我国农村劳动力的文化程度和人力资本存量在1990-2009年出现了双提高的局面。农村人力资本相对存量分布呈现较强的东西部空间梯度,造成这种差异的主要原因是地区经济发展差异。这种较强的东西部空间梯度能够解释农业生产率的区际差异和农村劳动力流动。     

中国海洋对外贸易发展与结构演变初探——基于WIND和WTO数据库的实证研究

近年来,海洋对外经济在国家对外经济中的地位日益提升,其发展对于推进海洋强国和贸易强国建设意义重大。本文初步探索了中国海洋对外贸易内涵与核算方法,利用WIND 和WTO 数据库,用沿海城市贸易依存度法和系数剥离法分别测算了中国海洋对外货物和对外服务贸易额。分析发现：海洋经济开放度日益提高,海洋对外贸易结构不断优化,贸易强国背景下海洋对外贸易应向科技兴贸、创新强贸方向转变,以此为民生改善、提振内需注入新活力。     

EFFECTS OF A CHILD'S DISABILITY ON AFFECTED FEMALE'S LABOUR SUPPLY IN AUSTRALIA

Australia has experienced a growing rate of child disability, with the rate of 3.7 per cent in 1998 increasing to 4.3 per cent in 2003 for children aged under four years and from 9.5 per cent to 10 per cent for children aged five to 14 years in the same period. However, surprisingly no study has examined the economic effects of child disability in the Australian context. This paper attempts to quantify the link between a child's disability and the work behaviour of the female in the affected family. Our findings provide empirical justifications for the current policy linking the severity level of child disability to the assessment of eligibility for Carer Payment (Child). We also found that child disability has different impacts on the labour market activities of married women and non‐married women. It appears that child disability imposes a greater hardship on non‐married women than on married women in terms of work choice decision. Once non‐married women manage to enter the labour force, they may have to stay on to work as usual even if they have a disabled child, because they may not have other family members to turn to for help as married women do.     

联合信用担保与科技型中小企业融资机制创新——杭州案例研究

传统的信用担保难以满足科技型中小企业巨大的融资需求。杭州市通过发挥政府资金的引导作用,对科技企业及银行、担保、保险、创投等进行资源整合,初步构建了一个集政策、产品、中介、信息服务于一体的综合性金融服务体系,形成了基于联合信用担保的运行机制和商业模式,在一定程度上化解了科技型中小企业面临的融资困境。     

西部大开发资本引入路径与经济增长实证分析——基于脉冲响应函数及方差分解的技术分析

利用我国西部地区各省份1990～2007年的固定资产投资来源数据,运用脉冲响应函数和方差分解技术,分析了不同资本对西部经济增长的影响。实证检验结果表明,不同渠道的资本引入与经济增长之间存在长期均衡关系,但其贡献率存在较大差异。因此,应在优化资本引入渠道、改善投资效果方面采取相应的措施。     

低保制度是地方性公共服务吗?

Government Expenditure Financing in a Two‐Sector Cash‐In‐Advance Model of Endogenous Growth

We show that an expansion in the government size could be desirable from the viewpoint of the economy's long‐run growth, wherein factor intensity between the sectors, the mode of public spending financing, and the form of the cash‐in‐advance (CIA) constraint are crucial. We also show that when real balances are required only for consumption purchases, money financing is equivalent to consumption tax financing, but is not equivalent to income tax financing. If both consumption and gross investment are liquidity‐constrained, then the three financing methods are mutually not equivalent. The optimal financing scheme has the following features: (1) when the CIA constraint applies only to consumption purchases, any combination of the money growth rate and the consumption tax rate that satisfies the government budget constraint constitutes an optimal financing mix; (2) when the CIA constraint applies to both consumption and investment purchases, consumption tax financing only is optimal.
