Localização das empresas do setor de tecnologia em Pernambuco: uma análise exploratória de dados espaciais

Abstract

The present research aims to analyze how technology companies are located, beyond the metropolitan region of Recife. For this, three variables were considered: total number of companies in the technology sector in the state, total number of employed persons and volume of salaries and remuneration paid. The data were obtained through the IBGE for the period between 2006 and 2019. The methodology used was the Exploratory Analysis of Spatial Data, which consists of detailing and visualizing the spatial distributions of the data studied, identifying, for example, if there are atypical locations (outliers spatial) and patterns of spatial associations (clustering and spatial clusters). More specifically, the methods used were univariate global spatial autocorrelation, which uses only one indicator for the entire region analyzed in order to find out if the data are randomly distributed or if they are linked to some systematic spatial pattern, through Moran's I coefficient. The other method is univariate local spatial autocorrelation, which checks whether global patterns of spatial autocorrelation can be associated with local patterns. The results indicated at first that the technology sector is losing its agglomeration characteristic in the Metropolitan Region of Recife, migrating to cities further away from the center such as Caruaru, Petrolina and Serra Talhada.
