FİRMA BÜYÜMESİ VE BÖLGESEL FARKLILIKLAR

Abstract

Firmaların nasıl büyüdüğü ve piyasaların nasıl şekillendiği iktisatta büyük ölçüde ilgi çeken alanlardan birisidir. Firma büyüklüğü ve firma büyümesi arasındaki ilişki; gelir ve iş fırsatlarının artmasına ve endüstriyel kalkınmanın gelişmesine olanak sağlayan kamu politikalarının tasarlanması için de önemli bilgiler sunar. Bu ilişki ilk kez Gibrat’ın (1931) tarafından incelenmiş ve sonrasında çok kapsamlı bir şekilde ele alınarak iktisat literatüründe Gibrat Yasası olarak yerini almıştır. Bu alanda yapılan çalışmaların büyük çoğunluğu, firma büyüklük-büyüme ilişkisini firmaların demografik özellikleri bağlamında ele almıştır ancak coğrafi konumun bu ilişki üzerindeki etkisi oldukça az ele alınmıştır. Bu çalışma, 2005-2015 dönemi için TÜİK Yıllık Sanayi ve Hizmet İstatistikleri Mikro veri setini kullanarak Türkiye’de bölgesel düzeyde (İBBS2) firmaların büyüklük dağılımını incelemeyi amaçlamaktadır. Çalışmanın temel bulguları firma büyüklük dağılımının, şekli ve evrimi açısından önemli bölgesel farklılıklar gösterdiği ve Gibrat yasasının öngördüğü log-normal dağılımdan oldukça uzak olduğudur.

FIRM SIZE AND REGIONAL DISPARITIES

Abstract

The relationship between firm size and firm growth has been extensively studied in economics literature following Gibrat's (1931) groundbreaking work. This relationship handled at micro scale is important for its macroeconomic consequences ranging from employment and income generation to industrial development. Basically, Gibrat's law argues that firm growth is independent of firm size. The argument suggesting that firm growth is heterogeneous by nature and that growth patterns depend on the demographic characteristics of the firm has been supported by many theoretical and empirical studies. However, the effects of geographic location of firms on firm dynamics and evolution have been subject to very limited research. This study aims to analyze firm size distributions by considering Gibrat’s law in a regional context. In the study, the size distributions of manufacturing firms and their evolution will be examined at NUTS-2 level for the period of 2005-2015. Using non-parametric technique of density estimation, we will test whether the empirical distributions of firm size approximates to log-normal distribution or not. The main finding of the study reveal that firm size distributions shows significant regional differences in terms of its shape and evolution and they’re far from the distribution stipulated by the Gibrat’s law.
