This paper presents an analysis of two renowned international arts festivals visitors' motives and profilecharacteristics, in two medium-sized Greek cities: the Kalamata International Dance Festival (KIDF) and theDrama International Short Film Festival (DISFF). The purpose of the study was to determine the reasons visitorsattend these festivals, which is necessary for building more concise marketing strategies and, therefore,more successful and sustainable events, with long-term benefits, ranging from the local to the national levels.The research addresses international arts festivals that share four main characteristics: (1) they host internationalprofessional artists; (2) they feature explicitly-stated artistic visions and objectives; (3) they are publicly funded;and (4) they have achieved a consecutive 23 years of successful presence in each city. These two case studiesrepresent two cultural events which have managed to maintain their popularity and high status, on the Europeanfestival map, as well as to raise their host cities' cultural and tourism standards, despite the serious economiccutback they have both faced. Due to limited available funds, the festivals lack marketing resources andspecifically data collection on visitor motivation, a gap which this study aims to remedy. Primary datawere collected with the aid of online structured questionnaires, distributed and collected during autumn2016. Altogether, 130 questionnaires were answered by visitors of the DISFF and 186 questionnaires wereanswered by visitors of the KIDF. Even though both festivals share similar characteristics regarding theirorganization and their aims, our analysis emphasized the heterogeneity of the motives of attendance in connectionwith the visitors' profile characteristics, for each event. While some similarities were found, especially betweendemographic sample characteristics and visitors' profiles, the general picture to emerge from the findingsindicates significant differences between the two cases. Arts festivals-goers do not appear to constitute a singlehomogeneous market; rather, each event appears to attract different audiences for different reasons. Theimplications of these findings, deriving from statistical analysis, are discussed and suggestions for further researchare outlined. This research aims to contribute to knowledge concerning the marketing strategies of internationalarts festivals in medium-sized cities, useful for research and academic purposes, as well as to local and nationalauthorities and other agencies and bodies, responsible for urban tourism and cultural city/town planning andmanagement. 展开更多

Compared with megacity, the medium-sized city is playing a more and more important part in the rapid urbanization process in China. Due to the expanding scale of the medium-sized city, urban growth is sprawl and this way leads to ecological, social and environment problems that are unsustainable. To measure the urban growth of the medium sized city, cellular automata (CA) model is employed. CA has proven to be a popular and effective modeling approach to investigate dynamic urban growth systems and for evaluating the impacts of possible policy options. We use the SLEUTH model, which is a well known CA model, to simulate the future urban growth of Huaian, Jiangsu province of China. The results confirm the value of SLEUTH which provides a rich exploratory of knowledge for evaluating the effects of possible decision-making in local government. 展开更多

The main task of this paper is to explore the housing condition and housing policy in the vast but long-neglected middle-sized cities in China. Under the requirement of "Construction of 10 Million Units in 2011" from the central government, the affordable housing has started its nationwide building. Medium-sized cities are facing different developing periods but applying same housing policy as big cities. The paper examines the economic and social condition of the case city to find out the housing problems. It concludes that houses are affordable in these medium-sized cities, but housing policies are not implemented well. The paper proposed that housing affordability in medium-sized city is not about quantity but about quality. To keep houses affordable in these medium-sized cities, housing market, legislation, urban planning, public participation and intensive developments are all important. 展开更多

By studying the relationship between urban development performance and city scale and regional difference, this paper aims at revealing the real challenges faced by small and medium-sized cities(referred to as SMSC hereafter) in China. It analyzes the growth of different-sized cities, their positions in China's overall urban system, the influence of city scale on their capability in migrant absorption, economic development, public service, and environmental remediation, as well as the capability difference among SMSCs. Results show that city scale is less a determinant in economic development capability and per capita ownership of public service than in economic performance, quality of public service, and environmental remediation capabilities. Besides, there are many other factors determined by regional differences instead of city scale. Therefore, in the context when SMSC plays an increasingly important role in the process of urbanization, relevant parties should avoid the "trap of scale," and re-position urbanization within the framework of sustainable development. 展开更多

Throughout the world,urbanization has been basically understood to refer to the process of increasing population flow from rural to urban areas.To adapt to this irreversible process,besides eradicating the urban-rural dual household system,China needs to accelerate the building of administrative system in small and medium-sized cities,which will enable them to absorb more migrants from rural areas,and thereby help ease the burden on large cities,and forge a sensible urban system.According to the statistics in this paper,by 2050,China’s urbanization rate will reach around 80%.This calls for as many as 1,050 small and medium-sized cities,i.e.,those capable of accommodating less than 500,000 residents.Currently,however,there are only 383 cities of that scale in China.Therefore,we need to think hard and clearly about how counties and towns are best developed under the urbanization drive,how to achieve optimal administrative structure through reclassification and adjustment of different administrative units,and how,in general,to enhance the quality of urbanization in China. 展开更多

In China, for small and medium-sized cities, urban and rural planning management should play an important role during the process of urbanization. However, it failed to do that in reality due to a series of limits, such as local fiscal deficiency, scarce human resources, incomplete management systems, historic planning defects, inadequate supervisions, and imperfect regulations, etc. This paper made a comprehensive analysis on the dilemma of urban and rural planning management in China's small and medium-sized cities and the interests and status of the government, enterprises and public in space resource allocation and put forward the methods to improve the quality of planning management in China's small and medium-sized cities from the view of systems and mechanisms. 展开更多

Urban traffic volume detection is an essential part of trafficplanning in terms of urban planning in China. To improve the statisticsefficiency of road traffic volume, this thesis proposes a method for predictingmotor vehicle traffic volume on urban roads in small and medium-sizedcities during the traffic peak hour by using mobile signal technology. Themethod is verified through simulation experiments, and the limitations andthe improvement methods are discussed. This research can be divided intothree parts: Firstly, the traffic patterns of small and medium-sized cities areobtained through a questionnaire survey. A total of 19745 residents weresurveyed in Luohe, a medium-sized city in China and five travel modes oflocal people were obtained. Secondly, after the characteristics of residents’rest and working time are investigated, a method is proposed in this studyfor the distribution of urban residential and working places based on mobilephone signaling technology. Finally, methods for predicting traffic volume ofthese travel modes are proposed after the characteristics of these travel modesand methods for the distribution of urban residential and working placesare analyzed. Based on the actual traffic volume data observed at offlineintersections, the project team takes Luohe city as the research object and itverifies the accuracy of the prediction method by comparing the predictiondata. The prediction simulation results of traffic volume show that the averageerror rate of traffic volume is unstable. The error rate ranges from 10% to 30%.In this thesis, simulation experiments and field investigations are adopted toanalyze why these errors occur. 展开更多
