In particular, our aim is twofold： （1） to provide measures of ICE specifically tailored to professional football businesses; and （2） to empirically investigate whether some dimensions of ICE, namely, human capital and relational capital efficiency, are positively associated with sporting performance, here used as a proxy for business performance. This paper develops a quantitative analysis of club-level panel data using the statistical technique known as mixed-effects linear regression for longitudinal analysis. The research spans a time period of five years and specifically the sporting seasons from 2007/2008 up to 2011/2012. The empirical findings of this study provide tentative evidence that ICE, especially as far as relational capital is concerned, is positively associated with on-pitch performance of professional football businesses. On the counterpart, results for the impact of human capital efficiency （HCE） do not consistently come out with the （positive） expected signs. More specifically, our findings suggest that relational capital efficiency, meaning the ability to develop and nurture positive business relationship with relevant external stakeholders, is a significant consideration for football club managers; on the other, they might shed light on the actual business model of professional football clubs that, in our analysis, does not appear consistent with the long-held hypothesis of winning maximization. The main limitation of this study lies in the fact that our indicators do not fully capture all relevant dimensions of the intellectual capital （IC） construct.展开更多

For this purpose, electricity-cost ratio (ECR) is proposed as the measuring parameter for the cost performance and a two-constant cost model is proposed to concisely describe the cost characteristic of the power generation as the opposite of a multi-constant cost model. Combination of the two-constant cost model and the ideal cell model developed recently produces an inclusive ECR equation that has three analytical expressions and thus allows of straight overviews of the cost performance evolutions in the working zones of the cells. The applications to real cells confirm the validity of the equation for operation optimization and technique evaluation of PEM fuel cells. And more insights into the cost performance evolutions are inferred by means of the equation to help promote the commercialization of PEM fuel cells.展开更多

This paper expounds an interior market network structure which is fit for the company intellectual capital operation, and analyses this organization pattern about the reasons of existence, the effectiveness of growing up in scale, the economies of knowledge distribution and the efficiency of operation, and it will provide some beneficial theoretical guidance about how can a company improve its competition competence in the knowledge environment through organization innovation.展开更多
