对市场导向、顾客资产导向与新产品开发绩效之间关系的探索性研究——基于中国背景的调节效应模型

当前,市场导向的收益和顾客资产的重要性已经得到了广泛的认同。然而,一方面有关市场导向的认识尚未达成共识,另一方面有关顾客资产的认识也出现了新的误区,而且尚未有文献对新产品开发绩效的复杂影响进行过系统的实证研究。本文旨在开发测量顾客资产导向的有效量表,并通过区分反应型市场导向和先动型市场导向,运用中国企业的实证数据揭示它们对新产品开发绩效的差异性影响,并检验了顾客资产导向对两种不同市场导向与新品绩效之间关系的调节作用,从而引导学者和企业家对市场导向和顾客资产导向的作用形成更为科学的认识。结果发现,顾客资产导向对新产品开发绩效的直接影响并不显著,但却可以对先动型市场导向与新产品开发绩效之间的关系产生积极的调节作用。     

基于浙东“唐诗之路”的剡溪山水文化旅游产品开发

民族地区高校课程资源的开发——基于“俱乐部产品”视角的分析

开发民族地区特有资源,形成民族地区高等院校特色专业及课程是当前民族地区高等教育发展的战略。民族地区拥有丰富而特殊的社会资源,加上高等教育具有“俱乐部产品”的外部性,课程资源开发有很高的可行性。但是,目前民族地区高等院校存在办学定位不正确、经费及人才短缺等问题,制约了课程资源的开发。吉首大学“研究基地（中心）+社会（单位或公司）+科研项目”的“三维一体”的课程资源开发模式有效地解决了上述问题,为民族地区高等院校课程资源开发探索了一条现实途径。     

A new measure of association for bivariate survival data

Time dependent association measures between variables are of interest in bivariate survival data. Several such measures have been proposed in literature for the modelling and analysis of survival data. In this paper, we introduce a new measure of association for bivariate survival data using product moment residual life function and mean residual life function. Various properties of the proposed measure and its relationship with existing measures are discussed. We also develop a non-parametric estimator of the measure and study its asymptotic properties. The application of the result is illustrated using a real life data. Finally, a stimulation study is carried out to assess the performance of the estimator.     

Limits to Concurrency*

In the global race to bring new products to market, many firms have adopted concurrent engineering as a technique to shrink development lead time. Due to the many concurrent engineering success stories in the business and engineering literature, a common misconception has grown that more concurrency is always better. The major contribution of this paper is a rigorous demonstration that limits to concurrency exist even in the simplified situation in which concurrency is modeled as the number of design modules to be executed in parallel. As complexities such as communication linkages between modules are layered onto our basic model, we show that the expected project completion time is minimized at a finite number of modules, a number that decreases with increasing problem complexity. In general, the more complex the project, the stricter the limits to concurrency. This strongly suggests that project managers should be cognizant of the potentially adverse effects of pushing concurrency too far.     

Agency conflict in diversified business groups and performance of affiliated firms in India: Contingent effect of external constraint and internal governance

This study examines how diversification in Indian business groups creates multiple forms of agency problems and has performance implications for group-affiliated firms. Departing from prior literature which emphasizes the principal–principal agency conflict in business groups, we argue that business group diversification leads to dual agency problems between controlling and minority shareholders (principal–principal) and shareholders and managers (principal–agent) in affiliated firms. Both these agency problems arise in diversified business groups through cross-subsidization of affiliated firms by inefficient capital investment, continuing presence of affiliated firms in declining industries, tunneling of resources from profitable affiliated firms, lack of attention by business group headquarters to affiliated firms, and affiliated firm managers' sense of perceived security, which negatively impacts affiliated firms’ performance. These agency issues are reduced with the increase in product market competition from exposure to international markets and through concentrated promoter ownership in the affiliated firms. Our hypothesized model finds empirical support in a sample of 828 business group–affiliated firms in India.     

R&D internationalization,product diversification and international performance for emerging market enterprises: An empirical study on Chinese enterprises

One motivation behind R&D internationalization for emerging market multinationals (EM MNEs) is to expand international markets. This paper analyzes whether the R&D internationalization of EM MNEs contributes to an improvement in international performance measured by foreign sales as a percentage of total sales (FSTS). Using panel data on China's listed companies, this paper introduces more scientific and normative indicators for measuring R&D internationalization in terms of geographic distribution (breadth) and overseas investment (depth). The results reveal an inverted U-shape relationship between R&D internationalization and international performance that is initially positive and eventually becomes negative. Product diversification has a significant moderating effect on the relationship between R&D internationalization breadth and international performance.

中国煤炭企业的全要素生产率增长

 本文通过Malmquist-Luenberger 指数将污染物及矿难作为“坏”产出纳入到全要素生产率的分析框架,测算了中国1998～2009 年30家大型煤炭企业的全要素生产率增长,并对影响全要素生产率增长的因素进行了实证分析。结果显示：“坏”产出约束下大多数企业的全要素生产率出现了负增长,但平均来讲企业的生产技术是显著进步的;在考虑环境污染及安全生产规制的两种不同情形下,分别有14家和16家企业发生过生产可能性边界的移动;技改和安全投入、管理效率以及滞后一期的技术无效率等因素与生产率指数呈显著的正相关关系,单位GDP煤炭消耗总量以及资本-劳动比与生产率指数呈显著的负相关关系,生产率指数与人均GDP呈“U”型关系。
