ABSTRACT. This paper develops a model to examine the economic interaction between central places and their hinterlands. The model allows interindustry linkages and upward trade flows in an urban hierarchy system. Trade balance equilibrium between hierarchical levels is established by direct mutual interlevel trade, rather than by indirect trade via the rural sector. The economic base multipliers generally increase with city size but occasionally they could be smaller than those of lower places. A continuous urban hierarchy is formed due to their relative location within the system, not to unspecified randomness.  相似文献

As a major contributor to local economies, the tourism industry has been greatly impacted by natural disasters. This study demonstrates the association between tourism economies and impacts of hurricanes in the southeastern United States containing coastal national parks, known for attracting a large number of tourists and having experienced hurricanes. In keeping with two longitudinal data methods (i.e. panel logit model and autoregressive integrated moving average), this study focused on the relationship between the (1) duration, intensity, and damage of hurricanes; (2) existing climate conditions; and (3) tourism demand on park visitation during hurricane and tourism seasons. As a whole, the impacts of hurricanes and climate conditions (precipitation, temperature) were found to have a negative effect on tourism demands (park visitation). With regard to the response of tourism economies to natural disaster damage, parks that experienced stronger natural disasters may be closed for a longer period in order to reconstruct facilities or natural/cultural resources damaged by storms. In an attempt to improve tourism-based regional economies, overcome the challenge of natural disasters on tourism economies, and increase opportunities for establishing disaster management, it is necessary to make an effort to allay unexpected damage to tourism-based areas through proactive plans for disaster mitigation activities.  相似文献

坟丘的区划盛土法是指在筑造坟丘时将其分成许多区域,由不同人力分别承担作业的筑造方式。为识别区划界限可设置异色粘土带、土囊列或排列石材作为标志物。坟丘的区划方向都是从坟丘中心呈放射状分布的,随着坟丘规模的扩大,区划数也在增多。中国春秋时期已使用区划盛土法这种技术,因而这种盛土方法应当是起源于中国。  相似文献

Wholesale clearance and eviction that typify China's urban development have often resulted in discontents among urban residents, giving rise to what critics refer to as property rights activism. This paper is an attempt to critically revisit the existing debates on the property rights activism in China. The paper refers to the perspective of the “right to the city” to examine whose rights count in China's urban development contexts and proposes a cross‐class alliance that engages both migrants and local citizens. The alliance itself will have substantial political implications, overcoming the limited level of rights awareness that mainly rests on distributional justice in China. The discussions are supported by an analysis of empirical data from the author's field research in Guangzhou, which examines how local and non‐local (migrant) residents view nail‐households resisting demolition and forced eviction.  相似文献

Chinese, Japanese, and Korean American families in the United States share several similarities, but they should not be interpreted as the sameness. Each group has gone through different immigration trajectories, and family members in a group have had different experiences. To get further knowledge of different family experiences in contemporary U.S. society, the trajectories of the family relationships among different Asian ethnic groups are examined. We specifically look at the time from arrival to World War II, from World War II to the 1960s, and after the 1960s.  相似文献

This study is a survey of Korean automobile manufacturers in Europe, which examines the different perceptions of emerging multinationals to economic integration and the subsequent strategic reactions relating to their particular characteristics. The findings show dissimilar patterns and motivations for Korean automotive foreign direct investment (FDI) when compared to those of established multinationals, which are conceptualized as a pre-emptive strategic advance, particularly in relation to the changing ownership endowments and negative perceptions of the single European market. These finding imply that conventional variables are unlikely to be applicable to emerging multinationals and show the need to segregate them from other multinationals when formulating industrial policies and firm-level competing strategies.  相似文献

The unseating of decks is one of the most prevalent failure modes of bridges after earthquake events, as observed in the 2010 Chile Earthquake. Damaged bridges in Chile often had skew angles and were supported on elastomeric bearings. Similar bridge construction practices with decks supported on elastomeric bearings are also common in the central and eastern U.S. (CEUS). The seismic displacement demands on skewed bridges are more complicated than those on bridges without skew angles due to the coupling of translational modes with the rotational mode of vibration. The study presented in this article seeks to understand the seismic response of skewed bridge decks supported on elastomeric bearings. The scope of the study is limited to one- and two-span bridges, which constitute a large portion of bridge inventory in the CEUS. The vibration modes of skewed bridge decks are derived in closed form and the modes are compared when the gaps between the bridge deck and the abutment are open and when one of the gaps is closed due to seismic excitation. Nonlinear response history analyses are carried out to understand the effects of vertical ground motion, skew angles, aspect ratios, and different ground motion types on the seismic displacement demand in these cases. Amplification factors that approximate the increase in the displacement demand due to the skew angle are proposed.  相似文献
