The aim of this research was to present and test a model of innovativeness improvement based on the impact of organizational learning culture. The concept of organizational learning culture (OLC) was presented and defined as a set of norms and values about the functioning of an organization (http://adp.fdv.uni-lj.si/opisi/inovtr09/povezana-gradiva/). These norms should support in-depth approaches aimed at achieving higher-level organizational learning. The elements of an organizational learning process that were used are information acquisition, information interpretation, and behavioural and cognitive changes. Within the competing values framework OLC covers some aspects of all four different types of cultures: group, developmental, hierarchical, and rational. Constructs comprising innovativeness are innovative culture and innovations, which are made of technical (product and service) and administrative (process) innovations. Datafrom 112 Turkish companies employing more than 50 people were used. The impact of OLC on innovations was empirically tested via structural equation modelling (SEM). The results showed that OLC has a very strong positive directeffect on innovations as well as moderate positive indirect impact via innovative culture.
