Abstract

This study examines how the power infrastructure quality affects manufacturing industry firms’ performance. To this end, panel data analysis is conducted on World Bank Enterprise Surveys, in which data of one hundred and thirty one thousand firms from one hundred and thirty nine countries covering years 2006–2017 is compiled. While performance and infrastructure indicators provided in the surveys for manufacturing industry firms are used as dependent and independent variables, respectively, some of the indicators related with finance, technology and firm characteristics are included to the analyses as explanatory variables. Empirical findings suggest negative and statistically significant effect of poor power infrastructure quality on capacity usage, an indicator of firm performance. Moreover, it is also found that unreliability on power infrastructure quality leads to increase in labor efficiency of the middle scale companies as well as of all the companies in middle-income countries.

Elektrik Altyapı Kalitesinin İmalat Sanayi Performansına Etkileri: Dünya Bankası İşletme Anketleri Üzerine Bir Panel Veri Analizi

Abstract

Bu çalışma elektrik altyapı kalitesinin imalat sanayindeki firma performansını nasıl etkilediğini incelemektedir. Bu bağlamda yüz otuz dokuz ülkeden yaklaşık yüz otuz bir bin firmanın 2006–2017 yılları arasındaki verilerinin derlendiği Dünya Bankası İşletme Anketleri kullanılarak panel veri analizi yapılmıştır. Anketlerde imalat sanayi şirketleri için verilen performans ve altyapı göstergeleri sırasıyla bağımlı ve bağımsız değişkenler; finans, teknoloji ve firma özellikleri ile ilgili göstergelerden bazıları ise açıklayıcı değişkenler olarak analizlere dahil edilmiştir. Ampirik bulgular elektrik altyapı kalitesizliğinin firma performansı göstergelerinden kapasite kullanımına negatif ve istatistiksel olarak anlamlı etkilediğini önermektedir. Ayrıca, orta ölçekli şirketlerde ve orta gelir grubu ülkelerindeki tüm şirketlerde elektrik altyapı kalitesine olan güvensizliğin emek verimliliğinde bir artışa sebebiyet verdiği gözlemlenmiştir.
