For every franchise system, making the leap from the unknown to the common place requires a strategic plan for growth. The exogenous market perspective holds that evaluating market conditions is central to defining promising outlet locations as there are direct economic effects on performance. The endogenous firm perspective and the social network approach together provide an inner strength perspective on interconnected firms; this perspective holds that access to resources offered at a certain spot determines site attractiveness, rather than location-specific market factors. Using a sample of 201 German franchisees, this study tests hypotheses that explore which perspective dominates location decisions in practice and clarify the relevance of the decisive criteria for outlet performance. Results show that location decisions rely on both perspectives, yet franchisee performance depends more on inner strength factors. We also find that expansion is better served by following a geographically dispersed cluster approach than by growing steadily from a baseline site.  相似文献

The article examines the network dynamics from franchising to licensing due to the increase of contractibility of the franchiser's system-specific assets as determinant of the allocation of decision rights between the network partners. Based on the property rights approach, residual decision rights must be allocated according to the distribution of intangible knowledge assets between the franchiser and franchisee. Our analysis derives the following hypothesis: The more contractible the franchiser's system-specific assets, the higher is the tendency from franchising toward licensing. In addition, we investigate the impact of strategy change on the standardization (contractibility) of system-specific assets and the network governance. We argue that a change of strategy may increase the contractibility of system-specific know-how and consequently the tendency toward licensing. This study presents empirical evidence from company Getifix on the network dynamics from franchising to licensing.  相似文献

In this study, a closed-circuit television (CCTV) system, installed for surveillance purposes, is utilized to measure the flow rate during a flood. The procedure to determine both the angle and scale-factor of the camera is described. Then, image analysis techniques, namely the direct visual measurement method, Large-Scale PIV (LSPIV) and Space-Time Image Velocimetry (STIV), are applied to the video images recorded by the CCTV camera. The results of these methods and the conventional float measurement are compared. In addition, the accuracy of the respective methods is discussed. A set of low-quality video images of a flood during a thunderstorm that occurred under the dark ambient conditions (midnight) is analyzed using three image-based methods. The transition of the flow rate during the event is successfully estimated.  相似文献

To come to terms with the realization of ASEAN+1, Taiwan had concluded with mainland China a special free trade agreement (FTA), the Economic Cooperation Framework Agreement (ECFA) in June 2010. This framework agreement provides an early harvest agreement of near-term tariff elimination, including detailed product schedules for goods and services from each side, with the final shape of fuller trade liberalization in goods and services taking years to negotiate and realize. The conclusion of the ECFA has been considered as a major breakthrough in cross-strait talks and economic relationships, even though it is by no means free from controversies inside Taiwan. The authors are therefore motivated by hot debates in Taiwan to reflect on the expected trade effect of the ECFA by taking into account the factor of cross-strait global production networks. In particular, we examine with a proposed model and statistical robustness, the trend of Taiwan-based firms' localization in mainland China, driven in part by constant movements in global production networks, which generates complicated and dynamic relationships between Taiwan's investment-induced trade and structural shift in Taiwan's exports to mainland China. Based on our empirical findings, we reflect on the conventional views on the trade effect of the free trade agreement. The results of our analyses tend to support a cautious view about the trade effect of the ECFA. Without denying the significance of the ECFA and deepening cross-strait economic relationships, we argue that the impact of the ECFA should be interpreted in a wider context than just the trade perspective, as the conventional wisdom and the existing evaluations suggested.  相似文献

市场转型过程中,大学生的就业体现出就业模式市场化,分配主体多元化,就业形势严峻化。以往研究较多关注社会资本对求职的具体作用,而忽略社会资本运作的深层问题探讨。通过个案调查认为,社会关系网络是求职的重要机制,强关系、弱关系在求职中都可能提供信息和影响,市场因素的介入引起"差序格局"变迁,物质性交易是弱关系提供影响的维系力,强关系和弱关系将在完善的制度环境中共同充当信息桥的角色。  相似文献
