Exploration and Exploitation in US Technological Change

چکیده
How do firms and inventors move through knowledge space as they develop their innovations? We propose a method for tracking patterns of exploration exploitation in patenting behaviour the US period since 1920. Our measure is constructed from text patents involves use Bayesian Surprise to how different current patent-based innovations are existing portfolios. results indicate that there distinct life-cycle firm inventor exploration. Furthermore, activity more geographically concentrated than general patenting, but this concentration centred outside main hubs patenting.

Group-Level Exploration and Exploitation
Organisational research has studied the tension between exploration and exploitation for years. In essence, this body of research agrees on the necessity of a balance between explorative and exploitative processes to prevent an organisation from falling into a learning trap. Thus, to enhance the active management of this balance in organisations, a deeper theoretical understanding of the factor...
متن کاملOn Evolutionary Exploration and Exploitation
Exploration and exploitation are the two cornerstones of problem solving by search. The common opinion about evolutionary algorithms is that they explore the search space by the (genetic) search operators, while exploitation is done by selection. This opinion is, however, questionable. In this paper we give a survey of diierent operators, review existing viewpoints on exploration and exploitati...
متن کاملExploration / Exploitation in Adaptive Recommender
Interactive information systems are often designed on the basis of little knowledge about users goals and about the final content of the information base. In addition users vary widely in their interests. This makes it useful to give such systems the ability to dynamically adapt to its users. Here we focus on ”recommending” systems that help a user navigate through the information system. In pa...
متن کاملBalancing Exploration and Exploitation in Alliance Formation
Do firms balance exploration and exploitation in their alliance formation decisions and, if so, why and how? We argue that absorptive capacity and organizational inertia impose conflicting pressures for exploration and exploitation with respect to the value chain function of alliances, the attributes of partners, and partners’ network positions. Although path dependencies reinforce either explo...
