入世五年我国银行业市场结构分析

2001年我国正式加入世界贸易组织,在银行业方面逐步取消对外资金融机构外汇业务服务对象的限制,相继开放若干城市的外资银行人民币经营业务,要素市场处于逐步开放之中.对此,文章通过采用哈佛学派的SCP范式,对入世五年来我国银行业的市场份额、市场集中度、产品差异以及产品进入壁垒等方面进行了分析,得出目前我国银行业进入壁垒高、创新不足、依然处于中等寡头垄断状态的结论.     

生态旅游与旅游生态化辨析

10多年来,生态旅游在中国的发展虽然很快,但理论上悬而未决的争论还较多,集中表现在生态旅游是旅游产品还是旅游发展模式、生态旅游是高档旅游还是大众旅游、生态旅游对象是自然区域还是可以包括地方文化区域等三个方面。同时在发展过程中,生态旅游在中国的实践中也出现了很多非生态化现象和"泛化"现象。这些现象的出现归根结底是由于将生态旅游与旅游生态化混为一谈造成的。本文通过对"生态旅游"、"旅游生态化"的辨析,对相关问题作了初步解答,并试图还原生态旅游的本意,探索今后生态旅游发展的正确途径。     

河北省红色旅游产品开发研究

针对2004年以来河北省红色旅游的发展历程，河北省红色旅游产品开发中主要存在缺乏市场调查、产品开发层次比较肤浅、红色旅游品牌产品比较缺乏等问题，结合红色旅游发展的目标和实际需求，提出河北省红色旅游产品发展应该注重规划的与时俱进、市场调研的充分性、深度开发以提高产品的吸引力及打造红色旅游品牌产品等适合于河北省红色旅游产品开发的对策。     

A Risk Analysis Model in Concurrent Engineering Product Development

Concurrent engineering has been widely accepted as a viable strategy for companies to reduce time to market and achieve overall cost savings. This article analyzes various risks and challenges in product development under the concurrent engineering environment. A three‐dimensional early warning approach for product development risk management is proposed by integrating graphical evaluation and review technique (GERT) and failure modes and effects analysis (FMEA). Simulation models are created to solve our proposed concurrent engineering product development risk management model. Solutions lead to identification of key risk controlling points. This article demonstrates the value of our approach to risk analysis as a means to monitor various risks typical in the manufacturing sector. This article has three main contributions. First, we establish a conceptual framework to classify various risks in concurrent engineering (CE) product development (PD). Second, we propose use of existing quantitative approaches for PD risk analysis purposes: GERT, FMEA, and product database management (PDM). Based on quantitative tools, we create our approach for risk management of CE PD and discuss solutions of the models. Third, we demonstrate the value of applying our approach using data from a typical Chinese motor company.     

顾客在新产品开发中的角色扮演研究

顾客在新产品开发(NPD)中具有越来越重要的作用,他们不仅仅是产品和服务的被动接受者,而且渐渐成为企业知识的主要来源。顾客在NPD中的作用可以用三个不同角色来描述:资源、使用者和共同创造者,并分析了在NPD过程中这三个角色所能发挥的作用。     

学术期刊开放存取的内在逻辑与发展趋势

学术期刊开放存取已经成为目前中国学术期刊界研究的热点问题，学术期刊的属性是分析学术期刊开放存取内在逻辑的前提和基础。从学术期刊的准公共产品属性出发，分析学术期刊开放存取的内在逻辑性，进而通过将开放存取与中国目前发展已相对完善的学术期刊商业数据库传播模式的对比，分析其在中国的发展趋势。分析认为，开放存取模式将不会取代商业数据库传播模式而成为中国学术期刊网络传播模式的主流。

Lattice path combinatorics for multiple product identities

Lattice paths are enumerated as walks on a lattice under the Delannoy criterion of vertical, horizontal and upward diagonal steps. Delannoy recursions are generalized for arbitrary weights in each of these directions, where the row elements of the Delannoy triangles correspond to lattice paths for all walks at a given length.     

Determining the effects of intraclass correlation on factorial experiments

This paper considers the effects of the presence of eqmi-correlation between observations in a k-way factorial experiment, A technique to provide unbiased F-tests is also constructed.
