Abstract
In the restructuring of the cities today, economic growth and its reflective trend multi-centred, urban development pattern made business enterprises shifted its locational choice in a decentralized way. As the focus of this paper, construction firms expended their market areas as well. The present study investigates the spatial distribution of construction firms according to the variables of socio-economic characteristics of districts and total construction sizes within the concept of multi-centre development in Istanbul. The paper describes the growth of the city and the construction firms through time according to the concentric zones and districts, firstly. Then descriptive figures and results of regression analysis are given by taking the number of construction firms as dependent variable and population, income per capita, average household size and amount of construction activity as the independent variables. Main hypothesis of this paper is that socio-economic indicators and total size of construction in building permits can explain the variance of number of construction firms in Istanbul district. Overall results from the multiple regression model indicate that the role of socio-economic indicators and total size of construction in building permits on the distribution of construction firms is proved on a large scale in the study. The spatial distribution of the construction firms has been figured out that the sub-central, peripheral districts of Istanbul have sustained the significant role in a way that responds to the construction supply, and housing sub-markets. However, the intense construction trends in the periphery reveal a fact that these firms preserve the location of their management offices in the sub-centre with relatively higher economic attraction, in central districts.
Highlights
During the last half-century, rapid population growth resulted in urban sprawl (Terzi and Bolen, 2009), restructuring of the city according to new technology and economic development and multicentre development (Dokmeci and Berkoz, 1994) and increased construction sector tremendously as well as the number of construction firms
Number of construction firm in district level, in Istanbul is used as the dependent variable, data of which is gathered from Istanbul Chamber of Commerce, Web Portal with the records of 2019
When defining the multi-centred development pattern in the spatial distribution of construction firms, 3.73% of these firms are located in core area (Fatih and Beyoglu); 32.83% are located in the intermediate zone (Bayrampasa, Besiktas, Eyup, Kadikoy, Sisli, Uskudar, and Zeytinburnu); and 63.44% in the periphery
Summary
During the last half-century, rapid population growth resulted in urban sprawl (Terzi and Bolen, 2009), restructuring of the city according to new technology and economic development and multicentre development (Dokmeci and Berkoz, 1994) and increased construction sector tremendously as well as the number of construction firms. The present study investigates the spatial distribution of construction firms according to the variables of socio-economic characteristics of districts and total construction sizes within the concept of multi-centre development in Istanbul. The paper by Maoh and Kanaroglou (2007) provides an empirical framework to illustrate the geographical clustering of firms in the City of Hamilton in Ontario, Canada According to their results, most of the firms are decentralizing i.e. the number of construction firms decreased from 6% to 4% between 1990 and 1997. In order to disclose the case of local level, the present study investigates the spatial distribution of construction companies according to the characteristics of districts such as population, income per capita and amount of construction by the use of multiple regression analysis in Istanbul. The final section is devoted to a conclusion and suggestions for further research
