Past research indicates that firm clustering improvesfirm performance by increasing levels of competitiveness and innovation amongfirms.While several studies have investigated the impact of co-locationon overall firm performance, few studies have examined the impact ofco-location on export levels. Using previous research, two hypotheses are developed, based on therelationship between export intensity and (1) location in a cluster, and (2)level of standardization of products.To test these hypotheses, data werecollected from 537 Canadian computer software firms listed by Industry Canada;these specific firms exhibited export sales, majority Canadian ownership, andcomplete information for the study's variables.The control variables ofthe studyandmeans of measuring the specific variables--e.g., exportintensity, co-location, and product standardization--are discussed. The results of the least squares regression of the data areexplained.The findings of the study indicate that co-location and productstandardization are positively linked to export intensity.However, thispositive relationship is only indicated for product-oriented firms and notforservice-oriented firms.(AKP)
