金融危机下股市网络的结构特性研究

利用复杂网络的方法,以各国股市为节点,以各股市问的关联性为边,建立起各国股市间的关联网络。通过Matlab编程计算研究了该网络的结构特性,分析出国际股市网络具有典型的小世界性和明显的社区结构,不具有无标度性。进而从网络结构上分析了金融危机的蔓延发生。并通过影响强度分析研究了中国股市在国际股市网络中的位置。     

中国页岩气开发的实质性突破

页岩气是指吸附在页岩中的天然气或自生自储在页岩纳米孔隙中连续聚集的天然气。新世纪以来,美国发生的页岩气革命影响了世界油气资源格局; 中国的非常规油气储存量非常可观,是世界上具有页岩气可采储量最大的国家; 但页岩气地质条件、水平钻井、分段压裂等技术储备和页岩气管理经验等还面临很大挑战。近年来,中国大力推进页岩气的开发利用,中石化、中石油和延长油田三家公司在示范区块开发的成功,以及短时间内在勘探开发方面取得的技术突破,标志着中国页岩气的开发已取得了实质性突破。但中国今后是否采取页岩气开发对多元资本开放的模式,还需要进一步研讨。     

中国风景名胜区交通可达性及市场潜力空间测度

基于旅游系统的区域开放性,从省内、省际两个角度出发,对国家级风景区的省内、省际交通可达性和市场潜力进行探讨。研究发现：① 风景区离散或集聚的规律性分布,使整体可达性区域差异性明显,呈现由东向西递减,由南北两侧向中间递增的分布格局。② 省内交通可达性优势区集中在东部沿海,省际交通可达性优势区集中在中原地区,与省内交通可达性相比,省际交通区域差异性更加明显,与航空可达性相比,铁路可达性对省际交通可达性的影响更大。③ 整体市场潜力呈现“带—团”状聚集式分布,基本形成了以东部沿海经济带为主的“带状”高市场潜力区,中部团状聚集式的较高市场潜力区,以及西部偏远低市场潜力区的空间分布格局。与省内市场潜力相比,省际市场潜力区域差异性更大,不同区域、种类的风景区省内、省际市场潜力优势不同。④ 旅游实际市场与市场潜力发展核心区空间错位明显,实际市场核心区主要集中在长江流域,市场潜力核心区则相对靠北,集中在中原及京津冀地区。     

贵州煤田地质局技术队伍建设问题探讨

目前地质市场由计划经济转化为市场经济,市场的竞争究其本质是人才竞争。因此应该采取科学合理的技术人才资源管理方法和管理体制,以整体和局部、近期和长远为目标进行有计划、有步骤的技术队伍建设,注重从才培养,激励地质技术人员专业技能的提高,采用倾斜政策留住人才、招纳人才,只有这样贵州煤田地质局才能在不久的将来拥有一支精干、高效的地质专业技术队伍,确保全局乃至二级单位适应煤田地质市场的需要,保证全局科学、和谐健康有序的发展。     

空间信息属性分辨率分析

在今天数字城市、数字政府等领域内大规模应用地理信息系统的时候,属性信息为主的应用成为地理信息系统必须要考虑的一个方向。属性信息的种类和多寡将直接影响这类地理信息系统的应用程度和应用深度．属性分辨率将是种类和单个种类数量的函数。属性分辨率有助于分析地理信息市场的结构和组织。     

Older People and Transitions from Employment to Nonemployment: International Perspectives and Policy Issues

The Organization for Economic Co-operation and Development (OECD) has identified population aging as one of the most important challenges facing OECD countries and has highlighted the need for people to work longer and for job prospects for older workers to be enhanced. This article provides a summary review of a recent OECD report, Ageing and Employment Policies—Live Longer, Work Longer, as a platform to highlight differences between countries in demographic profiles and projections and in patterns of formal labor market participation among older workers. Drawing on selected information from a broader evidence base, it unveils important differences between countries in the scale of demographic and associated labor market challenges. It also explores factors affecting labor market transitions among older workers and age-related and other barriers to paid work among older people, emphasizing the diversity of experience between individuals. Finally, it highlights some strategic challenges for policy.     

A multi‐dimensional analysis of the impacts of the Mahatma Gandhi National Rural Employment Guarantee Scheme: A tale from Tamil Nadu

This paper provides a multi‐dimensional analysis of the impacts of the Indian Mahatma Gandhi National Rural Employment Guarantee Scheme using a case study from rural Tamil Nadu. Drawing on structured interviews in households and semi‐structured interviews with local employers and officials, we analyse the effects of the workfare scheme when it is widely and properly implemented. We distinguish between different conceptualizations of the work scheme as a means of welfare provision, labour market policy and intervention directed towards other objectives. We found that the goals of the scheme were fulfilled unevenly in the given context. Among other findings, we show that positive effects on the welfare of participating and non‐participating households were accompanied by adverse effects on the local economy and negligible impact on out‐migration for work.     

The price for subway access: spatial econometric modelling of office rental rates in London

ABSTRACT

The relative location of commercial properties as the distance to the metro station as well as its absolute location as the address in the Central Business District (CBD) is expected to influence its valuation. We apply the advanced spatial econometric methodology, based on micro geo-located data, to the office rental transaction data from London in 2015. We use different spatial information on the local and global neighbourhood in order to estimate the spatial hedonic valuation model and test the strength of spatial spillovers and location effects on office fees. For offices in London in 2015, geographical factors may raise the price by 50%, as every next 100 m to the metro cost an additional 0.7 ? per ft² per year and the CBD location raises the cost for ca. 20 ? per ft² per year.     

Exploring Regional Firm-Size Structure in Canadian Housebuilding: Ontario, 1991 and 1996

This paper is concerned with the regional firm-size structure of housebuilding in Canada based on a case study of the province of Ontario. Using an innovative database of builders in Ontario and geographic information systems, measures of regional firm-size structure are developed and are modeled with data from the Canadian census. The results corroborate established models in the city systems and industrial organization literatures in that industrial concentration is negatively associated with regional population size, economic diversity, and economic performance. Small housebuilding firms abound in large, diverse and economically vibrant regions, especially large urban regions, and thereby maintain industrial deconcentration.
