The objective and justification of the chapter focuses on the importance that family businesses in Spain have in the current business environment, which is characterized by great instability. Also in the center of focus is how these family businesses integrate family values with a sustainable business. Innovation, technological advances, market internationalization, quality requirements, and the differentiation of products and/or services, among others, have led to important reflections on how to organize companies, especially family businesses. Nowadays and as a result of the economic crisis, it has been possible to observe a growing creation of family businesses in Spain, which reflects a driving role of business activity in its capacity to undertake and contribute to innovation. Thus, the figures provided by the Institute of Family Business in 2016 show that 90% of Spanish companies are family businesses and contribute about 60% of Spanish GDP and represent 70% of jobs in the private sector as a whole.
