The globalisation of retailing has intensified since the mid‐1990s with the rise of a group of international retailers. Foreign retailers have greatly impacted the Chinese retail market since the opening up of the retail sector in 1992. This study aims to examine spatial inequality and dynamics of foreign hypermarket retailers at different geographic scales in China. Although the relative gaps in foreign hypermarkets among Chinese regions are narrowing, the absolute gaps are widening. Logistic regression models are used to identify locational determinants of foreign retailers Carrefour, Wal‐Mart, and RT‐Mart at the intercity level. Carrefour prefers cities with larger urban district populations, longer time of being open to international retailers, and more foreign investment. While urban district populations are significant to Wal‐Mart and RT‐Mart as well, they favour cities where people have higher annual salaries and aim to achieve internal economies of scale at the provincial level. The three leading foreign retailers also have different first‐city and city size preferences in their provincial expansions.  相似文献

Past research on problem definition and public policy primarily focuses on the macro-system level. In this study, we propose a micro model of problem definition and policy choice at the individual level. We argue that while individual citizens' problem definitions and policy preferences are rooted in and filtered through their predisposition characteristics (such as socioeconomic status, political orientation, and informational base), their policy choices also strongly depend on how they define public issues, particularly how they perceive the image of an issue at hand and how they associate the issue with other public issues. Our empirical analyses, based on data from a national public survey on energy and power plant issues, support the key propositions derived from our theoretical model. Key contributions to and implications for policy studies are discussed in conclusion.  相似文献

In the Gulf lowlands, Late Classic fluctuations were concomitant with the increasing importance of the Classic Veracruz style complex. A characteristic feature of the style was ballgame imagery on ballcourt panels, molded ceramics, and paraphernalia such as yokes, hachas, and palmas, as well as courts, markers, and stelae. Components of the Classic Veracruz style have been documented for the Gulf lowlands and adjoining regions of Mesoamerica. Few examples, however, derive from stratigraphic excavations of in situ deposits. We document the discovery, excavation, and initial interpretation of a monument-yoke-offering complex at Matacanela, located in the south-central Tuxtla Mountains. We present suggestive evidence for associated decapitation ritual. We conclude by assessing these data and generating hypotheses regarding the transitioning of authority. We situate the Matacanela complex within regional demographic, political, and economic transformations that occurred throughout the Classic period (ca. a.d. 300–800/1000), culminating in disruptions that may have been contentious.  相似文献
