安徽区域科技基础条件平台建设面临的问题与对策探讨

区域科技基础条件平台建设是一项复杂的系统工程,建设工作分为基础性工作和特色性工作的提法有助于地方政府分析条件平台建设的重点和难点.科技条件平台的核心功能之一是以科技资源共建共享的方式向社会提供共性技术尤其是产业共性技术.地方政府解决科技资源供给和需求之间的矛盾的关键在于对共性技术范围进行界定以及确定如何供给共性技术.     

积分循环赛在学校篮球竞赛中的应用研究

为了在学校篮球竞赛中引入积分循环赛，文章针对棋类积分编排存在的三个方面问题，通过采用每轮比赛排名作为配对排序的条件，并对棋类积分编排方法进行了一定的简化移植，经过多次试验性编排，运用电子表格技术设计出了一整套篮球积分编排方法。这种方法可实际运用于篮球积分循环赛的手工编排，并能为实现计算机篮球积分编排提供理论依据。     

从无锡看区域性网上商店的经营策略

网上商店在经营中普遍遇到了商品交易数量少、无传统资源支撑及高成本运作等困难,区域性网上商店要发展必须对其本身有一个战略的认识,并能解决好成本控制问题。对于区域性网上商店,除了要提供价格优惠的商品外,还应该坚持本地化发展,坚持地域性和业务性联合,并采用商品价格依据配送时限而定的物流配送体系,从而有效降低配送成本,最终实现区域性网上商店从生存到发展的目的。     

China＇s Regional Disparity and Its Policy Responses

The fruits of China＇s rapid economic development over the 3 decades have not been distributed fairly across different regions. Using data from a sample of 815 Chinese listed firrns during 1998-2004, our error-correction investment model showes evidence of different financial constraints on firms＇ investment in different regions. We argue that China＇s regional development policies have contributed greatly to the regional inequalities. To control the rising inequality, China has shifted its focus from the coast to the interior regions. However, it is becoming increasingly difficult for the government to direct the economy, as market mechanisms now have afar greater influence on the economy than the government does. The people-centered approach of the current leadership has meant that substantial attention has been placed on regional development disparities in an attempt to build a ＂harmonious society. ＂ China needs further extensive reforms if all the measures for reducing regional disparity are to be effective.     

China's regional income disparityAn alternative way to think of the sources and causes1

Using data on China's provincial economies for the period 1978–2005, we decomposed the causes and factors that have contributed to inter‐regional per capita income disparity. Variance in capital per employee and variance in capital elasticity are found to be the two main sources of income disparity while the employment–labour force ratio is shown to be an important factor in containing the rise of income disparity. An analysis on inter‐regional factor reallocation effects reveals their relatively small and insignificant contributions to overall growth performance. It is also discovered that capital has in most years flowed in the right direction to pursue higher marginal productivity across provincial economies. Inter‐provincial labour movement, on the other hand, had not displayed significant equilibrating effects until institutional reforms started to allow freer inter‐regional labour mobility in later years. Generally, we conclude that market‐oriented factor mobility has played a crucial role in equalizing factor returns as well as enhancing growth efficiency across regions.     

基于客户关系管理的企业业务流程重组

在全球经济一体化环境下，传统的管理模式、经营理念、业务方法已不能适应快速变化的市场运行。顾客（Customer）、竞争（Competition）和改变（Change）驱使企业发展进入新阶段。在灵活性与快速响应主宰的商业战场中，客户关系应用而生，业务流程重组和客户关系管理的结合似乎成了一种必然．     

区域经济发展差距:新经济地理、要素流动与经济政策

改革开放后,中国区域经济发展差距主要表现为区域间差距的扩大,而非区域内部差距的扩大。这一现象的发生是多方面原因共同作用的结果:在新经济地理因素的影响下,具有区位优势的东部沿海地区吸引了中西部地区大量的生产要素进行跨区域流动,加上中央政府的政策导向作用,使得中国经济发展差距呈现出逐步扩大的趋势。因此,中央政府应该采取有力措施,以便在全国形成合理的区域分工,进而达到缩小区域经济发展差距的目标。

A theory of innovation for process-based innovations such as nanotechnology

Many see Nanotechnology as the technology that will underlie the next Schumpeterian wave creating new opportunities for wealth and job creation. Further it is a process based or materials technology. Yet all currently used models of innovation are based on assembled products or service products and these simply do not recognize the differences in materials products nor the “enabling” nature of Nanotechnologies. If nanotechnology is poised to become the economic engine of this millennium and if current models of innovation, which are utilized, by policy makers and firm based strategist alike are based on technology product paradigms that are dissimilar to the realities of nanotechnology and other process-based technologies then there is cause for concern.Here the authors provide a model and supporting cases demonstrating a new process or materials based innovation model that is based on the tight coupling between product and process innovation of not only Nanotechnology-based products but other process-based products. This is an important finding, because it identifies and remedies a gap in the literature associated with earlier process and product innovation models. For process-based products like materials, food, chemicals and nanotechnologies any change to the manufacturing processes results in significant changes in end product features. The implications of this model to practice are considered.     

The adequacy of asymptotic approximations in the near-integrated autoregressive model with dependent errors

We consider the normalized least squares estimator of the parameter in a nearly integrated first-order autoregressive model with dependent errors. In a first step we consider its asymptotic distribution as well as asymptotic expansion up to order O_p(T⁻¹). We derive a limiting moment generating function which enables us to calculate various distributional quantities by numerical integration. A simulation study is performed to assess the adequacy of the asymptotic distribution when the errors are correlated. We focus our attention on two leading cases: MA(1) errors and AR(1) errors. The asymptotic approximations are shown to be inadequate as the MA root gets close to −1 and as the AR root approaches either −1 or 1. Our theoretical analysis helps to explain and understand the simulation results of Schwert (1989) and DeJong, Nankervis, Savin, and Whiteman (1992) concerning the size and power of Phillips and Perron's (1988) unit root test. A companion paper, Nabeya and Perron (1994), presents alternative asymptotic frameworks in the cases where the usual asymptotic distribution fails to provide an adequate approximation to the finite-sample distribution.
