黑龙江省发展现代化大农业的理论思考

在今后一定时期,发展现代化大农业是黑龙江省农业和农村经济发展的主题和战略任务。现代化大农业首先是现代农业,其次是具有“大”字特征的现代农业,其中“大规模”是发展现代化大农业的物质基础,“大组织”是其经营主体,“大农机”是生产工具,“大科技”是生产手段,“大服务”是保障体系,“大市场”是支撑条件,“大产业”是实现形式和发展理念,“大产出”是发展目标和必然结果。     

我国大中型工业企业创新能力地区差距及变迁——基于1999-2010年面板数据的分析

本文采用1999-2010年我国30个省市面板数据,利用改进的TOPSIS法和锡尔熵分解模型测度了我国大中型工业企业的创新能力区域差距及变化趋势。研究结果表明,就总体而言,我国大中型工业企业创新能力表现出较大的空间差异性,区域差距显著并呈扩大趋势;从区域内部差异来说,东南地区、大西南地区及大西北地区大中型工业企业创新能力省际差距较大,长三角地区和中部地区省际差距较小;对我国大中型工业企业创新能力区域差距影响最大的因素是组间差距,而组内差距影响相对较小。     

大比例尺土地变更调查引发的思考

针对当前大比例尺土地变更调查工作强度大、效率低、人工操作复杂的问题,采用个案研究和定性分析的方法,分析了土地变更调查的主要调查内容和影响大比例尺土地变更调查工作效率的关键环节;提出了对大比例尺土地变更调查地区可通过关联业务来控制日常用地管理信息的测绘精度,从而避免由测绘限差引起的影响土地变更调查效率的缝隙和碎面问题;国土资源管理部门应加强对变更软件开发的指导,从而有效降低由于技术与管理脱节而增加的变更工作量。     

民营大企业转型的利益相关者研究

公司治理能力、技术创新能力、企业管理水平、对产业链的控制能力是民营企业转型发展的主要目标。民营大型企业在转型发展过程中与利益相关者构成了一个价值网络。民营大企业转型的目标应是在此价值网络的构建中发挥与巩固平台领导者的地位。同时,民营企业还需要完善相应的治理结构,进行机制再创新,管理再升级,经营再改善,市场再拓展,产品再换代等方面的转型升级。民营企业转型的本质就是在重新调整各种利益关系的基础上,企业获得自身发展所需的资源基础上获得更快的发展。     

Nowcasting Chinese GDP: information content of economic and financial data

This article applies the factor model proposed by Giannone, Reichlin, and Small (2005 Giannone, D., Reichlin, L. and Small, D. 2005. “Nowcasting GDP and inflation: The real time information content of macroeconomic data release”. In Finance and Economic Discussion Series 2005–42, Washington, DC: Board of Governors of the Federal Reserve System.  [Google Scholar]) on a large data set to nowcast (i.e. current-quarter forecast) the annual growth rate of China's quarterly GDP. The data set contains 189 indicator series of several categories, such as prices, industrial production, fixed asset investment, external sector, money market, and financial market. This article also applies Bai and Ng's criteria (2002) to determine the number of common factors in the factor model. The identified model generates out-of-sample nowcasts for China's GDP with smaller mean-squared forecast errors than those of the random walk benchmark. Moreover, using the factor model, we find that interest rate data is the single most important block of information to improve estimates of current-quarter GDP in China. Other important blocks are consumer and retail prices data and fixed asset investment indicators.     

Perfect option hedging for a large trader

Standard derivative pricing theory is based on the assumption of agents acting as price takers on the market for the underlying asset. We relax this hypothesis and study if and how a large agent whose trades move prices can replicate the payoff of a derivative security. Our analysis extends prior work of Jarrow to economies with continuous security trading. We characterize the solution to the hedge problem in terms of a nonlinear partial differential equation and provide results on existence and uniqueness of this equation. Simulations are used to compare the hedging strategies in our model to standard Black-Scholes strategies.     

Investment Guide to Qingdao

Qindao is the host city for several events of the 2008 Olympics, including the sailing competitions which will take place along the shoreline by the city. The unique architecture combination of German and Chinese in the city centre, the German demographic roots and a large Korean expat population, give Qingdao a distinct atmosphere. Too many eye-ball catching strengths turn the beautiful seashore city into an attractive place in foreign investor＇s eyes.

The Core of Large Differentiable TU Games

For suitable non-atomic TU games ν, the core can be determined by computing appropriate derivatives of ν, yielding one of two stark conclusions: either core(ν) is empty or it consists of a single measure that can be expressed explicitly in terms of derivatives of ν. In this sense, core theory for a class of games may be reduced to calculus. Journal of Economic Literature Classification Number: C71.     

项目成功标准研究的动态演变与启示

项目成功标准是正确评价项目成功与否的前提。本文立足于4种不同的观点——传统、财务、客户/利益相关者和系统观点,对国内外成功标准研究的既有成果进行了梳理。结果表明,对项目成功标准的研究从单一的铁三角标准正逐步向更系统化的标准动态演进,基于全寿命周期思想和利益相关者视角下的项目成功标准可从项目管理绩效、项目初评价绩效、项目组织战略绩效和项目完成绩效4个维度为大型工程项目评价提供系统化、整体化的评价依据。
