宁海县中堡溪治理工程防洪堤施工质量控制措施分析

防洪堤工程的施工质量直接决定着堤防两岸人民的生命、财产安全,因此其施工质量控制措施的分析就显得尤为重要。本文结合宁海县胡陈乡中堡溪治理工程一期工程施工全过程的实例,分析了从施工前、施工中等方面的施工质量控制措施,供同类工程参考。     

爱，使他健康成长

作为一名教师,我一直认为对孩子的教育中心理健康教育是很重要的一部分,因为拥有完善的人格才能更好地生活,知识再渊博也比不上孩子的心理健康重要。孩子是祖国的花朵,家长是花朵的阳光,教师是花朵的雨露,孩子的成长与阳光、雨露是密不可分的,给孩子再多的物质遗产不如给孩子一个健全的人格,健全的人格对孩子一生都是取之不尽的。     

Product market competition and cost stickiness

Extant literature on cost stickiness has focused on how firm-specific characteristics affect the asymmetric cost behavior. In this paper, we explore how a firm’s operating environment affects the firm’s cost stickiness. Specifically, we examine the effect of product market competition on cost stickiness since a firm’s investment and cost retention decisions partly depend on how the firm interacts with its rival firms in the product markets. Using two firm-level text-based product market competition measures extracted from management disclosures in firms’ 10-K filings (Li et al. in J Account Res 51(2):399–436, 2013; Hoberg and Phillips in Rev Financ Stud 23(10):3773–3811, 2010; J Polit Econ, 2015), we find strong evidence consistent with cost asymmetry increasing in competition after controlling for known economic determinants of cost stickiness. In additional analyses, we also find that the effect of product market competition on the degree of cost stickiness increases in firms’ financial strength, likely because management in financially stronger firms has more resources for investment expenditures in spite of a sales fall. We also find that cost stickiness is increasing in competition if management is optimistic about future demand, whereas competition is not associated with cost asymmetry if management is pessimistic about future demand. Finally, we find that the relationship between competition and cost stickiness, although statistically insignificant at conventional levels, is more pronounced for single-segment firms relative to multi-segment firms.     

Public capital, endogenous growth, and endogenous fluctuations

Cazzavillan [Cazzavillan, G., 1996. Public spending, endogenous growth, and endogenous fluctuations. Journal of Economic Theory 71, 394–415] studies a discrete-time, one-sector endogenous growth model with a flow of publicly enjoyable goods and productive services financed through income taxation. He demonstrates how equilibrium paths are indeterminate, for a large range of the consumption externality of public spending. This study extends [Cazzavillan, 1996] by considering an otherwise identical production function, except with public capital stock as an input. The results support the robustness of multiple growth paths even in a one-sector growth model with public capital stock, and modify the set of the consumption externality of public spending, in determining growth dynamics in a similar model with non-accumulated public spending.     

Unemployment and welfare consequences of international outsourcing under monopolistic competition

This paper challenges the conventional academic view that international outsourcing is just another form of gainful trade. Contrary to that view, we show that labour‐service outsourcing can reduce the high‐wage country's welfare even when product‐market trade is beneficial, within a model that combines involuntary unemployment and monopolistic competition. Outsourcing's impact on welfare is worsened by a definite loss of jobs and a possible contraction in the range of varieties produced worldwide. While owners of capital benefit from outsourcing under certain conditions, labour's welfare always falls.     

浙江省各县市服务业吸收劳动力情况的实证研究

服务业是未来吸收劳动力的主要途径。文章主要通过聚类分析将浙江省各县市按照本地劳动力在服务业的分配分成几类,然后再分别对这几类的数据进行主成分分析,找出它们在服务业领域的比较优势,进而根据分析结果得出结论。浙江省的各个县市在服务业发展方面都具有各自的潜力与主要发展方向,未来浙江省的三大产业比重会调整到“三、二、一”的局面,服务业在吸收劳动力方面将发挥更加巨大的作用。     

众包、众筹、众创——高校科研模式创新研究

互联网的普及催生了众包、众筹以及众创等大众创新形式,将有力促进高校科研创新模式向开放式、现代化转变。从论述高校科研模式创新的必要性和合理性出发,提出解决科研团队、科研教师、科研学生面临问题的新思路及运作机理,即借助互联网技术,构建高校科研众包平台、科研众筹平台以及科研众创平台。建议依托三大平台,有效利用各方科研资源,广泛筹集社会研究资金,充分发挥智力资本价值,加大政策支持和制度规范,以促进高校科研模式健康发展。     

论建设资源节约、环境友好型城市

节约发展、清洁发展是落实科学发展观的必然要求,本文从国情分析与国际竞争的视角,阐明了节约资源、保护环境作为基本国策的根据;指出了城市在贯彻两项基本国策中的重要地位,以及如何将其贯穿于城市长远规划和日常城市管理中.     

政治资源、经济资源与收入差距

在制衡机制缺位的前提下,政治资源和经济资源的扭曲结合恶化了资源分配的不平等,它是居民收入差距和地区收入差距扩大的重要原因。文章认为,解决政治资源分配不均以及由其导致的经济资源分配不均,即实现政治资源和经济资源的合理结合,对缩小收入差距有积极作用,也是进一步值得研究的重要课题。
