招商引资竞争的有效性分析

本文利用一个简单的模型分析了区域招商引资竞争的有效性，在竞争的状态下，除区域间收益差额超过潜在不利的情况外，潜在不利区域将很难利用优惠改变企业固有区位，竞争使得分配更加有利于企业而不利于参与招商引资竞争的区域，而且这种招商引资竞争是难以避免的。认清本区域既有优势和关键行业比单纯提供优惠在招商引资过程中更加重要。     

Cooperative R&D and the Value of the Firm

In this paper, we investigate the stock price responses of listed firms in the U.S. markets to announcements of R & D collaborations. We find that abnormal returns of stocks are significantly positive after R & D collaborations are announced. The positive stock price response towards the R & D cooperation initiations can be partially explained by the nature of the collaborations and the characteristics of the participating firms. We also find that the stock prices of rival firms respond negatively to announcements of R & D cooperation. This result seems to support the hypothesis that cooperative R & D improves economic efficiency of the cooperative firms that gain competitive advantage. We do not find evidence supporting the hypothesis that R & D cooperation creates collusive, anticompetitive effects in the product market.     

Information transmission and causality in the Italian Treasury bond market

We examine causality and efficiency in the Italian T-bond market, where cash trades take place on the domestic Mercato Telematico dei Titoli di Stato, while futures trading is based on the London International Financial Futures Exchange. We find evidence that causality in prices runs in both directions, and that the cash lead is almost comparable in size and extension to the futures lead. We then try to assess whether the cash market is weak-form efficient with respect to LIFFE prices. Using a simple trading rule with a variety of time and price filters, we conclude that the observed lead cannot be exploited to make a profit after transaction costs.     

巴江口水电站综合办公楼防雷设计方案

随着现代社会的发展，建筑物的规模不断扩大，其内各种电气设备的使用日趋增多，尤其是随着计算机网络信息技术的普及，建筑物越来越多采用各种信息化的电气设备。广西每年因雷击破坏建筑物内电气设备的事件时有发生，所造成的损失非常巨大。因此，建筑物的防雷设计显得尤为重要。笔者结合实际工作，以巴江口水电站综合办公楼防雷设计为例，提出建筑物综合防雷工程设计方案。     

论国有企业转变机关作风提高机关效率建设

国有企业担负着经济责任、社会责任和政治责任,因此,国有企业机关既有别于政府部门机关,又有别于一般企业行政部门机关。文章结合笔者所在单位的机关特点,从如何认识机关作风建设的重要性和必要性引出机关作风建设应坚持＂三个面向＂,体现＂四个一流＂,以及从多方面阐述落实机关作风建设的具体措施。     

Land management for erosion prevention: A case study for a Turkish nature reserve

As a result of landslides and soil erosion, a substantial amount of soil has been lost in Turkey. Particularly, fertile lands have long been faced with the threat of erosion, largely as a result of traditional (unplanned) land use practices. This threat is more evident in the Black Sea Region with its rough topography and rainy climate. The basic reason for this threat is the lack of organization in land use planning and control. Although proposals, in the context of this requirement, are included in national development plans, they have not been implemented. Accordingly, in this study research based on spatial data evaluation was carried out for Sera Lake located in Akcaabat, Trabzon, Turkey. For this purpose, temporal area, depth and volume changes of the lake were determined by utilizing topographic maps, aerial photographs and hydrographical measurements. To evaluate determined changes in the size of the lake and to produce suggestions to legislators for required sustainable land management activities, information on land use/cover types, land ownership and climate in the vicinity of the lake was utilized. As a result, it was determined that the area, depth and volume of the lake were significantly decreased during the last decades, as a consequence of erosion mainly caused by traditional land use practices; thus, the lake is threatened with the danger of extinction due to erosion. Precautions required for the alleviation of erosion and other adverse environmental effects which largely seem to be caused by harsh physical properties (caused basically by topography) of the region were discussed. In support of the information inherent to the region, traditional arable land use was logically determined as the basic non-natural factor (which is directly prone to erosion) to be rearranged in the context of sustainable land management. In this context, beyond nationwide actions (national agricultural policy and Soil Protection and Land Use Law), which may provide the required land management tools in the long term, it is proposed that planning and accordingly land management activities specific to the study area (Sera Valley) should immediately be commenced in close collaboration with the related public (owners or farmers). However, behaviours of different types of land users (engaged in commercial, subsistence and semi-subsistence farming) and also high number of owners and/or farmers (caused by small pieces of land parcels owned/used in shares) make the desired collaboration almost impossible. This socio-economical problem may be solved by further developing the current land registry and cadastre system in terms of customary land use rights, land use/cover changes and updating procedures.

New Zealand Bank Mergers and Efficiency Gains

ABSTRACT

This paper uses accounting ratios and DEA (Data Envelopment Analysis) to explore the efficiency impacts of 6 bank mergers in New Zealand between 1989 and 1998. The paper is the first reported application of DEA to the New Zealand banking sector, and its methodology is based around that used by Avkiran in his study published in the Journal of Banking and Finance in 1999 (Avkiran, 1999b).

Consistent with earlier research, acquiring banks were found to be generally larger than their targets, although they were not consistently more efficient. In a majority of cases the merger led to an increase in efficiency, consistent with a trend observed for the banking sector as a whole. No clear conclusions could be drawn on possible public benefits from the mergers.     

金融业技术效率的参数法估计

本文基于1995～2010年金融业投入和产出的数据,利用参数法中的随机前沿方法,估计金融业的技术效率变化情况。这些官方发布的数据要比在假设下估计的数据更加有说服力,估计结果更加可信。研究发现我国金融业的平均效率很高,约为0.95,在2003年和2008年两年有两个下降的过程。研究还发现,市场化程度与财政支出对金融业的效率有促进作用。     

政府采购制度:强化财政支出管理的必由之路
