چکیده

در دو دهه اخیر توسعه چندمرکزی توجه زیادی را در ادبیات نظری و اسناد سیاسی به سوی خود معطوف کرده است. طرفداران چندمرکزیتی معتقدند این الگوی فضایی می­تواند توازنی را میان اهداف متناقض رقابت­پذیری اقتصادی، انسجام اجتماعی و پایداری محیطی در مقیاس­های مختلف ایجاد کند. تا به حال، مطالعات زیادی به بررسی اثربخشی و کارایی فرضیات مطرح شده در ارتباط با ساختارهای چندمرکزی پرداختند اما پژوهش­های انگشت شماری به بررسی ارتباط میان قیمت زمین و استطاعت­پذیری مسکن توجه کردند. در این راستا، ابتدا استان­های کشور با دو شاخص پراکنش فضایی و توزیع اندازه شهرها مورد سنجش قرار گرفتند. و سپس با استفاده از رگرسیون دو متغیره ارتباط آنها با شاخص­های قیمت زمین، رشد قیمت زمین و استطاعت­پذیری مسکن بررسی شدند. یافته­های پژوهش از الگوهای فضایی چندمرکزی حمایت می­کند. به طوری که میان پراکنش فضایی شهرها و توزیع اندازه شهرها و قیمت زمین ارتباط مثبت و معناداری وجود دارد. همچنین پراکنش فضایی متوازن مراکز شهرها در پهنه سرزمین می­تواند تا حدودی رشد قیمت مسکن را کنترل کند. به علاوه، بین شاخص­های چندمرکزی و استطاعت­پذیری مسکن ارتباط نسبتا محکم و معناداری پیدا شده است. بنابراین، به نظر می­رسد ساختارهای چندمرکزی می­توانند در زمان اوج تاب­آوری بیشتری در برابر رشد قیمت مسکن داشته باشند.

چکیده [English]

In the last two decades, polycentric development has attracted much attention in the theoretical literature and political documents. Polycentric advocates that spatial pattern can create a balance between conflicting goals of economic competitiveness, social cohesion, and environmental sustainability on a large-scale. So far, many studies have looked at the effectiveness and efficiency of hypotheses raised to polycentric structures, but few studies have considered the relationship between land prices and affordable housing. In this regard, first, the provinces of the country were measured with two indicators of spatial and city size distribution. Then, using a bivariate regression, their relationship with land price indexes, land price growth and affordability of housing were investigated. Research findings support polycentric spatial patterns. So there is a positive and significant relationship between the spatial distribution of cities and the distribution of cities and land prices. Also, the balanced distribution of urban centers in the territory of the land could partly control the growth of housing prices. In addition, there is a relatively strong and significant relationship between polycentric and affordable housing indices. Consequently, polycentric structures seem to be more resilient in higher housing prices at peak times.
