ABSTRACT

This paper studies the impacts of urban renewal on local residents’ place identity by examining the changes in local residents’ place identity in Sunwenxilu, a traditional commercial street in downtown Zhongshan City, Guangdong Province, China, which carried out urban renewal relatively early in modern China. Applying Breakwell’s [(2015). Risk: Social psychological perspectives. In J. D. Wright (Ed.), International encyclopedia of the social & behavioral sciences (2nd Ed.). New York, NY: Elsevier] identity process model and using the renewal process as a starting point, data concerning local residents’ place identity in Sunwenxilu were collected through in-depth interviews, observations, and literature analysis. The results reveal that local residents had established a strong place identity on Sunwenxilu before it changed to be a community of “incompetents” in the 1990s. In the late 1990s, Sunwenxilu was transformed into a cultural tourism pedestrian street. Right after the transformation, local residents regained their self-esteem with the improvement of the physical environment and intensification of cultural symbols, and re-established their place continuity by maintaining their collective memories. However, a failure to improve the local residents’ self-efficiency of place during the “superficial” renewal had resulted in vulnerability of the local residents’ place identity in terms of self-esteem, continuity and distinctiveness, thus causing another crisis of place identity. Obviously, the construction of place identity results from the interaction of all elements, so too much emphasis on only one element may trigger a new identity crisis.  相似文献

The development of state farmland preservation policies has primarily relied upon results of the Census of Agriculture that is updated every 5 years by the USDA National Agriculture Statistics Service. Questions about the suitability of the Census of Agriculture center on the measures of total farmland and total cropland as reported by agricultural producers. The reliance on these variables fails to distinguish between conversion to developed uses and other fluctuations in the total availability of farmland. This inability to directly measure farmland conversion to developed uses has been shown to influence state level farmland preservation policies. The policies of Illinois and Indiana highlight the disparate approaches, with Illinois pursuing an intensive policy to protect farmland and Indiana choosing to not address farmland preservation at a state level. In order to assess the suitability of the different approaches to farmland preservation policy it is critical to evaluate the Census of Agriculture data used to justify the policies of Illinois and Indiana.  相似文献

城市土地空间结构演变及其驱动机制分析   总被引:11,自引:0,他引:11  
城市土地利用空间结构及其演变一直是城市地理学、城市经济学、城市规划学、土地利用学等学科研究的核心与热点问题.当前我国城市土地利用正处在快速城市化的开端,在未来近半个多世纪的时期中,将一直处于急剧突变进程之中.加强对我国城市土地空间结构演变及其驱动机制的研究,有助于我们从城市用地结构演变的根源分析问题.本文简要概括了城市土地利用空间结构的相关研究,分析了城市用地空间结构演变在空间上的两种表现形式,并在此基础上分析了城市用地空间结构演变的动力主体、驱动力和驱动机制,以期为更好地促进城市土地利用结构的优化提供相应的参考.  相似文献

This paper assesses the potential implications on off-season tourism of enhancing the cultural offer of Rimini, a popular Italian seaside holiday destination hosting about 12 million overnight stays per year. Since more than 9 million of these stays are concentrated in the summer season, in the last 20 years. Rimini has been undergoing a policy of seasonality smoothing, which mainly pivots around business and cultural tourism. This assessment has been carried out through discrete choice experiments submitted to a sample of about 800 tourists who visited Rimini outside the summer months. Since tourism can be viewed as a composite good, which overall utility depends on how the component characteristics are arranged, the choice experiments allow to disentangle the importance and the willingness to pay of tourists for different attributes of the holiday. The choice model incorporates a number of possible changes to actual tourism features (which are also the subject of public debate), including them in hypothetical alternative “holiday packages”. The conditional logit analysis of the choice experiments can highlight any synergy or trade-off between cultural and business tourism. Results suggest that business and leisure tourists share many features related to the use of the territory, while there are important trade-offs between these two groups and cultural tourists. Since business tourists have a higher willingness to extend their stay, a softer budget, and their demand is also complementary to the demand of summer tourists (Brau, Scorcu, & Vici, 2009), from the destination point of view investing in this market segment would be the best option. Although a “second best”, however, cultural tourists share with the local population of Rimini many aspects of the demand of territory (Figini, Castellani, & Vici, 2009). Hence, cultural tourism can play a fundamental role in the intermediate season as a tool for smoothing seasonality, to diversify investments and to give value to the city’s cultural heritage.  相似文献

The objective of this paper is to analyze the loyalty of tourists to urban tourism destinations, studying the differences existing on the basis of nationality of origin. The review of the academic literature identified perceived value and satisfaction as antecedents of loyalty. A theoretical model was constructed which was tested empirically with a total of 927 surveys of Italian and American tourists in the city of Barcelona. In the study of the data, structural equation models (SEM) were used, by means of a multi-group analysis. The empirical results show that the causal relationships among perceived value, satisfaction and loyalty and the moderating effect of nationality are partially confirmed. This study contributes to better knowledge of the processes that lead tourists to be loyal to an urban tourism destination.  相似文献
