Spatial Analysis of Physicians' Offices with Respect to Population and Hospital Beds in Istanbul

Maldistribution of medical staff is a subject of criticism in many developing countries. This paper investigates the spatial distribution of physicians' offices with respect to population and hospital beds in Istanbul. The spatial distribution of physicians' offices is investigated with respect to socio-economic and locational characteristics of the districts. The results show that only a few districts benefit from an amazing growth in the concentration of physicians' offices while the periphery of the city, where mostly low-income people live, has a lower physician/population ratio than the metropolitan average. In addition, the spatial distribution of physicians offices with respect to population and hospital beds is investigated by the use of regression analysis within time. According to the results, while there was some relationship between the physicians' offices and the hospital beds in the 1980s, there was no relationship with population or hospital bed distribution in the 1990s. Increasing the number of factors which affect the distribution of physicians and testing the model in other metropolitan areas in order to obtain more general results are suggested for further research.     

Spatial Distribution of Shopping Malls and Analysis of their Trade Areas in Istanbul

This paper investigates the spatial distribution of shopping malls with respect to population and analyses the factors which effect the shopping mall location. According to the results, while the shopping mall space ratio is higher than population ratio in the intermediate zone, the reverse is true in the periphery. The relationships between the shopping mall space and income, population and distance to the central business district (CBD) of the locations are investigated by the use of regression analysis. The results reveal that income is the only factor affecting the location of shopping malls among those considered. In addition, three shopping malls from the inner and peripheral zones of Istanbul were analysed with respect to frequency to shopping centres and characteristics of trade areas. According to the results, the size of the catchment area of the shopping mall from the inner zone is larger then the peripheral ones due to higher accessibility with alternative transportation systems and supporting functions in its surrounding areas. The results fall within the concept of central place theory. Further research is suggested by expending the study to the other areas of the city with different characteristics to calculate their retail potential and their spatial implications.     

Transformation of Istanbul from a monocentric to a polycentric city

This paper investigates the spatial transformation of Istanbul from a monocentric to a polycentric city following the growth of the city and the development of its communications systems. The population and employment of peripheral districts have been growing rapidly, while those of the core districts have decreased. In addition, other variables are utilized for the identification of polycentres such as tax revenues from commercial enterprises, weighted average trip length and volume of mail. The results of the study reveal that the old CBD of Istanbul is no longer a dominant employment centre. Instead, a new CBD is emerging at the intersection of the radial and the peripheral highways, and subcentres are developing in some of the first and second ring districts. A major contributing factor to Istanbul's polycentric development has been the transformation of its economy into one that requires large modem office space and facilities for private automobiles—both of which are difficult to provide within the old CBD. In addition, the construction of peripheral highways has contributed to a pattern of polycentric development. Moreover, there is a desperate need for planned development of these subcentres in order to prevent their current haphazard development and to give a character to the peripheral areas of Istanbul.     

论我国城市化过程中的城乡文化整合

早期的城乡隔离制度造成了我国现存的城乡文化"二元结构",从而极大地影响了城乡文化的交流与发展。因此,必须进行城乡文化整合。本文就城市化过程中,影响城乡文化整合的因子进行了灰色关联度分析,得出了各因子对城乡文化整合进度的影响强弱排序;并且提出了通过加强小城镇的建设来推进我国的城乡文化整合,其中主要包括加快发展小城镇乡镇企业和发展小城镇文化产业。笔者认为,发展小城镇文化产业应该从四个方面入手:第一,增大小城镇文化教育及科技投入。第二,立足提高小城镇人口的文化素质,增加文化整合的底蕴。第三,建立城市帮扶小城镇的长效机制,加快推进城市文化的扩容和普及。第四,拓宽融资渠道,建设小城镇文化产业。     

The determinants of county growth

The determinants of population and employment growth were explored from a broader interregional (as opposed to intraregional) perspective. Data for the 1970s, at the county level of disaggregation, were used to analyze the effects of economic, demographic, and climatic variables on population and employment growth in a simultaneous equation framework. The use of data from the more than 3000 US counties provides a considerably larger testing ground than those used in previous research. The point of departure was a conventional, general equilibrium model in which both households and producers are geographically mobile. The study's dependent variables refer to population, total, and manufacturing employment densities. Family income had a powerful effect in stimulating both population and employment density. A 10% increase in family income led to a 7.9% increase in total and a 9.2% increase in manufacturing employment densities. High family income must stand for high demand, and thus, firms are drawn to an area. High family income also drew households to an area. A 10% increase in family income led to a 5.5% increase in population density. High family income must represent "good" neighborhoods for households. High family income was positively correlated with population and employment density, but in other recent studies either a negative and significant relationship or an insignificant relationship were reported. Local taxes consist of the receipts of county government and those of municipalities, townships, school districts, and special districts within the county. The elasticities reported in Table 4 suggest that a 10% increase in such taxes resulted in about a 0.072% reduction in county population density during the decade. The Industrial Revenue Bonds (IRBs) and the percent of the labor force that is unionized are 2 potential policy instruments at the state level. The study results suggest that IRBs have not stimulated either manufacturing or total employment, and the coefficients were statistically insignificant in the structural equations. The elasticities imply that a 10% increase in percent union reduces total employment by 0.42% and manufacturing employment by 0.18%. The effect on population was tiny. Further, while not intended, the interstate highway program may have been a significant redistributor of population and employment but has not caused immigration of people and jobs from central cities.     

Determinants of Residential Location Choice: How Important Are Local Public Goods in Attracting Homeowners to Central City Locations?*

Abstract. A hybrid conditional logit choice model is estimated using data on the characteristics and destination of homeowners who engaged in intrametropolitan moves among 17 school districts within the Columbus, Ohio area in 1995. The model is used to test the relative influence of local fiscal and public goods versus household‐level characteristics in determining household location choices across central city and suburban school districts. Results provide evidence of both a “natural evolution” of households to the suburbs, due to job location, residential filtering, and household income and lifecycle effects, and “flight from blight,” due to lower school quality, higher crime levels, and lower average income levels in the city. In comparing the magnitudes of these variables, we find that school quality exerts the strongest influence: a 1‐percent increase in the school quality of the city district increases the probability of choosing a city residence by 3.7 percent. In contrast, the effects of household income and other individual characteristics are relatively modest. The findings provide support for a “flight from blight” suburbanization process that is dominated by differences in neighborhood quality between the city and suburbs. An implication is that investments that promote central city development and reduce suburbanization are justified on efficiency grounds if negative externalities are generated by increased concentration of poverty, crime, and low school quality.     

Property and Personal Crime in Istanbul

In recent studies on urban safety, close relationships between physical and demographic characteristics have been found in crime levels in cities. In many countries social, political and economic turmoil have been the main reasons for the increase in urban crime and violence in the last 50 years. In physically deprived environments, the most important factors that increase urban crime are socially isolated communities, economic discrimination and lack of equality in political citizenship rights. In developing countries, it is difficult to obtain data about crime and safety. For this reason, there are very few studies on crime compared to developed countries. In the research in this paper, the similarities and differences of crime ratios against property and persons in Istanbul are compared with those in other countries. For this purpose, the spatial distribution of crimes committed were analysed on a comparative basis between 1998–2002 in 32 districts displaying different characteristics in terms of distance to the centre, use of land, value of land, physical and demographic features. The research revealed that the crime rates in Istanbul against property and persons were in parallel with developed countries. The districts which have mixed use (residential and commercial, residential and industrial), high population increase, high number of households, high density and high land value, property and personal crime levels are high; when date of becoming a district is recent and the size of the district is large, property and personal crime levels are low.     

Spatial Analysis of Residential Prices in Istanbul

The purpose of this paper is to examine the spatial distribution of housing prices at the metropolitan and at the district level of Istanbul. At the metropolitan level, the most important factors which affect housing prices are sub-market, floor area and sea view. At the district level, housing prices vary from district to district according to locational, socio-economic and property characteristics. High-income sub-markets have higher coefficient of determinations and more significant variables than low-income sub-markets. Furthermore, the results suggest that planned districts have higher housing prices; thus, restructuring squatter areas and revitalizing inner city areas provide not only benefits to individuals but also higher tax revenues to the city.     

Urban Restructuring of Istanbul

After 1980s, the major cities of Turkey have experienced urban transformation process following the changes in the international trade policy and the impact of globalization. Istanbul took the highest amount of share from these transformation processes as being the most important economic, cultural and tourism centre and the most integrated centre to the world economy of the country. This paper describes Istanbul's historical development, investigates demographic profile and spatial distribution of employment and illustrates multi-centre development of the city. Decentralization of population and jobs illustrate the multi-centre development. Multi-centre development contributes to sustainable urban development which provides efficient energy use and prevents pollution. Istanbul having a long history, large population and being in a very strategic location between Asia and Europe greatly effected from globalization which is reflected in its transformation of urban structure and increased land values and thus offered great opportunities for the real estate investors. The role of Istanbul within the world hierarchy of cities is suggested for further research.     

EDUCATION AND INCOME INEQUALITY IN THE REGIONS OF THE EUROPEAN UNION*

ABSTRACT This paper provides an empirical study of the determinants of income inequality across regions of the EU. Using the European Community Household Panel dataset for 102 regions over the period 1995–2000, it analyses how microeconomic changes in human capital distribution affect income inequality for the population as a whole and for normally working people. The different static and dynamic panel data analyses conducted reveal that the relationship between income per capita and income inequality, as well as between a good human capital endowment and income inequality is positive. High levels of inequality in educational attainment are also associated with higher income inequality. The above results are robust to changes in the definition of income distribution and may be interpreted as a sign of the responsiveness of the EU labor market to differences in qualifications and skills. Other results indicate that population ageing, female participation in the labor force, urbanization, agriculture, and industry are negatively associated to income inequality, while unemployment and the presence of a strong financial sector positively affect inequality. Finally, income inequality is lower in social‐democratic welfare states, in Protestant areas, and in regions with Nordic family structures.     

Factors Influencing Location Selection of Warehouses at the Intra-Urban Level: Istanbul Case

Depending on the worldwide developments in the industry and services sectors, the increased significance of the logistic sector is continuing. In parallel to this tendency, the need for warehousing as one of the basic activities of logistics has increased and the warehouses have returned to the important function areas for urban sites. In recent years, warehouses are demanded in the real estate market just like houses and offices. In the literature, although there are many supply chain studies focused on location selection of warehouses, there is a lack of studies discussing the behaviour of warehouse location at the intra-urban level. The article investigates the factors affecting the location selection of warehouses and their degree of importance in Istanbul as a case area by using a logistic regression model. It was found that location-specific factors are effective on the location selection of warehouses in the Istanbul metropolitan area, and warehouse location follows a certain economic rationality at the intra-urban level.     

广州城市公共服务设施供给空间分异研究

转型期以来,政府治理制度的变革及公私部门关系的重构使我国城市公共服务设施供给主体、供给机制逐步多元化,其分布形态也由空间均衡趋向分异。本文以广州为案例,研究结果表明:广州城市公共服务设施分布总体上呈核心-边缘空间格局,区域供给规模差异大且与人口分布不相协调,区际及不同类型设施的空间聚集水平差异显著;传统计划经济条件下城市公共服务设施空间均衡分布模式被市场经济条件下高收入地区指向的集中布局模式所取代,表现出类似西方国家城市公共资源配置的"反比例服务法则"。     

Spatial Analysis of Library System and Proposal for New Libraries in Istanbul

Over the past several decades, the rapid growth of Istanbul has resulted in a tremendous gap between the need and provision of social facilities. Growing societal and community needs in the information age and the desire to become a member of the European Union (EU) have stimulated public officials to upgrade the existing libraries and to increase their numbers so as to reach European standards. Thus, the purpose of this paper is to evaluate the spatial distribution of existing libraries and to propose new ones where they are needed. Volume is the most important and the population of the districts is the second important factor to affect library use. Thus, it is crucial to support library construction, especially in the periphery of the city for future development, and to improve the level of service of the existing libraries.     

Local and regional income differences in Finland in 1989 to 1997 — a GIS approach

Income differentials among the population of Finland began to widen in the latter half of the 1990s, as reflected in a geographical analysis based on 1 × 1 km grid cell data produced by Statistics Finland, where the most densely populated cells are seen to have lower mean income levels than the others, and the spatial differences in income level within the large towns and cities are seen to have increased. The income differentials between grid cells are fairly stable and the majority of the cells can be classified as representing the middle income bracket in terms of incomes subject to state taxation. Accurate geo-referenced data of this kind enable observations to be made concerning income differentials which would remain obscured if only administrative areal units such as local government districts were used.

Population density and the accuracy of the land valuations in the 1798 federal direct tax

Abstract

The peculiar operation of the 1798 federal direct tax has led scholars to question whether tax officials reported the land valuations from their districts faithfully. Peter Lindert and Jeffrey Williamson argue that southern tax assessors systemically under reported the value of southern real estate, and they adjust their income estimates to account for the likelihood of corruption. This paper affirms the reliability of the tax returns by demonstrating that population density, rather than corruption or lax enforcement, can explain nearly all of the variation between the assessment districts. Accepting the tax valuations as accurate would lower Lindert and Williamson’s income estimates, imply slower growth rate between 1774 and 1800, and suggest a higher growth rate between 1800 and 1850.     

Beautiful city: Leisure amenities and urban growth

Modern urban economic theory and policymakers are coming to see the provision of consumer‐leisure amenities as a way to attract population, especially the highly skilled and their employers. However, past studies have arguably only provided indirect evidence of the importance of leisure amenities for urban development. In this paper, we propose and validate the number of tourist trips and the number of crowdsourced picturesque locations as measures of consumer revealed preferences for local lifestyle amenities. Urban population growth in the 1990–2010 period was about 10% points (about one standard deviation) higher in a metro area that was perceived as twice more picturesque. This measure ties with low taxes as the most important predictor of urban population growth. “Beautiful cities” disproportionally attracted highly educated individuals and experienced faster housing price appreciation, especially in supply‐inelastic markets. In contrast to the generally declining trend of the American central city, neighborhoods that were close to central recreational districts have experienced economic growth, although at the cost of minority displacement.     

城乡一体化过程中聚落选址和布局的演变

城乡一体化是区域经济发展到一定阶段的产物,它在客观上表现为聚落选址和布局的演变:即在发达地区表现为居民聚集区由点状分布趋向面状分布,在欠发达地区表现为由点状分布趋向线状分布。这种聚落选址和布局的演变是城乡一体化过程中经济发展的必然结果,受着影响经济发展的因素的制约;然而,聚落选址和布局演变又是影响经济发展的一个重要因素,制约着区域经济的发展。在城乡一体化过程中,现代交通取向,现代市场取向、现代工业取向和现代人口取向是聚落演变的重要推动力,影响聚落选址和布局的基本格局。不同的聚落选址和布局对区域经济的发展有着加速或延缓的作用。     

Community Pharmacies in the City Area: Evidence from an Italian Province

Pharmacy opening and pharmacy location are heavily regulated in Italy. This paper investigates how pharmacies are positioned in the city area and analyses the role of some factors relevant for gaining access to pharmacy services and competition. For this purpose, a probit regression model has been estimated. A main finding is that the spread of pharmacies all over the city area is unbalanced. The number of residents in the surroundings is not a main determinant of location. In spite of the availability of competing outlets nearby, pharmacies tend to be situated in areas attracting visitors as part of the working and travel circuits. This contributes to good access to the extent to which consumers can easily get to the pharmacy from the doctor's office as well as from work or shopping. However, while multiple outlets are available in the areas offering better business opportunities, the other parts of the municipal district are often unsupplied. As a result, accessibility within the city area is not the same for all residents. Several aspects of the overall pharmacy market regulation prove unsuited for opposing this pattern of location.     

Exploring The Basis For Parental Choice in Public Education

From the perspective of public choice theory, this article explores the relationship between student performance and certain aspects of school organization and operation. Employing multiple regression and analysis of variance techniques, we found that variation in comprehensive student assessment test scores can be explained best by variables such as income, district size, and the extent of classroom crowding. Student performance was lowest in the largest districts. Student performance tended to be better in those school districts with relatively higher incomes, fewer schools, and a lower proportion of oversized classes. These findings confirm the utility of readily available information about public schools as a basis for parental choice and lend support to public choice criticism of large, centralized, educational organizations.
