有机生长理念下物流园区弹性布局方法初探

物流园区作为城市中特殊的功能区,对提升城市经济结构、完善城市功能布局、促进资源有机整合有着积极的促进作用。然而,物流园的发展是一个动态过程,既包括应对市场环境变化所产生的自身功能优化,又包括应对城市空间扩张所产生的城市功能置入,因此,合理的园区空间布局规划应具备一定的弹性。本文基于有机生长理念,从功能分区、用地分类、道路交通、地块划分等方面对物流园区的弹性布局方法展开探讨,以期为科学合理的园区规划提供一定的技术支撑和借鉴。

Antecedents and consequences of knowledge sharing in international tourist hotels

The purpose of this empirical study is to investigate factors which influence knowledge sharing, organizational learning and effectiveness. Of self-completed questionnaires collected from international tourist hotels in Taiwan, 615 were usable for data analysis. The structural equation modeling results showed that leaders played the roles of mentor, facilitator and innovator, and nurtured a supportive environment at the levels of workgroup, immediate superior and organization. In addition, employees had a positive attitude towards learning and to sharing. All of these contributions facilitate transformation of collective individual knowledge to organizational knowledge, resulting in the advancement of organizational learning, and thus, greater organizational effectiveness.     

Policies to support ethnic minority enterprise: the English experience

Using Global Entrepreneurship Monitor data for 29 countries this study investigates the (differential) impact of several factors on female and male entrepreneurship at the country level. These factors are derived from three streams of literature, including that on entrepreneurship in general, on female labour force participation and on female entrepreneurship. The paper deals with the methodological aspects of investigating (female) entrepreneurship by distinguishing between two measures of female entrepreneurship: the number of female entrepreneurs and the share of women in the total number of entrepreneurs. The first measure is used to investigate whether variables have an impact on entrepreneurship in general (influencing both the number of female and male entrepreneurs). The second measure is used to investigate whether factors have a differential relative impact on female and male entrepreneurship, i.e. whether they influence the diversity or gender composition of entrepreneurship. Findings indicate that – by and large – female and male entrepreneurial activity rates are influenced by the same factors and in the same direction. However, for some factors (e.g. unemployment, life satisfaction) we find a differential impact on female and male entrepreneurship. The present study also shows that the factors influencing the number of female entrepreneurs may be different from those influencing the share of female entrepreneurs. In this light it is important that governments are aware of what they want to accomplish (i.e. do they want to stimulate the number of female entrepreneurs or the gender composition of entrepreneurship) to be able to select appropriate policy measures.     

汇率形成机制与做市商制度:动因、成本分析

人民币汇率形成机制问题成为近年来国际经济事务中的焦点.中国外汇交易中心2005年5月推出8种外汇交易品种以及引入外币间交易做市商制度,这一举措成为观察、试验做市商制度的序曲.本文研究认为,外汇市场引入做市商制度有利于改善人民币汇率形成机制,但是由于我国外汇市场还不完善,引入做市商制度也会带来一定的成本.为了全面推广做市商制度,多方面配套问题尚待解决.

Urban vs. rural destinations: Residents’ perceptions,community participation and support for tourism development

This paper investigates and compares the effects of residents' perceptions of the impacts of tourism on community participation and support for tourism development across urban and rural world heritage sites (WHSs). Partial least squares – structural equation modeling (PLS-SEM), has been employed to perform the analysis. The results reveal significant differences between the effects of residents' perceptions and community participation on support for tourism development in urban and rural destinations. However, the findings did not support any differences between the effects of positive perceptions on community participation, and the indirect effects of negative perceptions on support for tourism development. This study makes a significant theoretical contribution to the urban and rural tourism and residents’ perceptions literature by comparing rural and urban WHSs residents. Furthermore, this study has a number of practical implications for the local authorities of rural and urban WHSs.
