This paper analyses tourism firms’ performance, as a measure of their competitive strength through financial results, comparing family business with nonfamily business. This study is justified by the important role of the tourism sector in the Spanish economy and its prospects for global growth, as well as its structural features derived in part by the significant weight of family-owned business. The economic results have been measured on the basis of the return on equity of the company, its sales growth and market share, its production efficiency, and its financial solvency. The objective results indicators come from the company itself or two secondary databases: SABI and INFORMA D & B. The ex-post analysis is completed with other competitiveness indicators based on self-assessment by the managers in relation to their competition, captured through a primary study with a sample of 1,019 companies.
