This report attempts to survey Korean public sectors' innovation activities and characteristics alongside with Korean Manufacturing and Service industry innovation survey tradition. As a pilot survey, 2011 Korean public sector innovation survey conducted on the sectors of Health service and Social Welfare service with categories of product/service innovation, process innovation, organizational innovation, communication innovation. Moreover, innovation performance, innovation inputs, innovation process, innovation capabilities, innovation networks and barriers to innovations are surveyed. The results show that 1) innovation activities are driven by their own wills mostly by top-level decision makers, 2) the incidents and levels of innovation activities are quite behind European Nordic countries, 3) open innovation activities are low, and innovation partners are mostly public authorities and research institutes but international cooperations are rare. 4) The most barriers to innovation was budget constraint and their budgets are mostly come from central or regional governments. The characteristics of Korean public sector innovation can be categorized into that 1) all innovation activties are primitive stages and are not widely diffused into each organizations, 2) service innovation is only about quality control not about diverse innovative service creations and service delivery cost-down, and 3) porcess innovation happens in the form of new equipments introduction but not with new innovation planning and feasibility studies, surveys and feedbacks.
