Despite the growing importance of developing countries to the global economy and their increasing role in innovation, limited academic attention has been given to the national innovation systems (NIS) of these countries. Given that they commonly suffer a lack of resources, efficiency in the operation of innovation seems crucial. This study aims to assess the innovation efficiency of developing countries. Breaking down the NIS into two stages, knowledge production and application process, we additionally introduce the knowledge absorption perspective in the latter stage as the consideration for the context of developing countries. Based on the results of the efficiency assessment, clustering analysis is implemented to identify several typologies of the operation of NIS in developing countries and to provide implications for each case. This study will constitute a meaningful attempt to provide a general understanding of innovation status and operations in developing countries, thereby suggesting policy directions for several cases.

Purpose
– The purpose of this paper is to examine how user-perceived video quality, measured by computer assisted web survey, interacts with content richness (CR) and interactivity (IA). It also analyzes how those internet protocol television (IPTV) idiosyncrasies impacts audience perceptions (perceived usefulness (PU) and perceived resistance (PR)) and actual subscriptions.


Design/methodology/approach
– A computer assisted web survey was administered in Korea to collect data. A structural equation model and Z-test analyses were conducted to address the research hypotheses.


Findings
– User-perceived video quality influences audience perceptions (PU and PR) through interaction with CR and IA. Subscriber perceptions have a causal relationship with IPTV subscriptions.


Practical implications
– Balanced improvement of the IPTV value chain, from content to technical (platform, network, and terminal) perspectives, are necessary for IPTV diffusion. Also, IPTV providers should establish the diffusion strategies, minimizing the user-perceived restrictiveness as well as maximizing the PU.


Originality/value
– This study shows computer assisted assessment of video quality can be applied to behavior science. The research model suggests PR, which has been relatively unnoticed is included in existing technology acceptance theories. The introduced antecedents of IPTV subscriptions can be referred to as key performance indicators regarding new media adoption studies.

Information and Communications Technology (ICT) has become a necessity in social and economic development and is a leading sector to enable and drive growth in other sectors in Cambodia such as education, agriculture, and health. Recently, the mobile telecom service market in Cambodia has demonstrated rapid growth, which is jumping off the fixed-line, with a penetration rate of 75.27% of the total population by the end of 2010. Despite this rapid growth rate, the mobile telecom service market in Cambodia faces a number of key challenges. There seems to be excessive competition in the mobile telecom service market due to the number of operators (eight active operators). In the short term, this market favors demand side rather than supply side by lowering prices. Consumers' welfare increases with the lower prices resulting from heavy competition. Also the dominant market players gain relatively higher profits while those of the less-dominant players have been squeezed by increasing market polarization. Furthermore, there is a lack of sector policy framework, Telecommunication Law, which means government Ad hoc regulations are implemented in the market to resolve the issues. These factors will contribute to market failure and lower market efficiency in the long run. This study examines the competitive environment of the mobile phone market in Cambodia to identify what the challenges are and how to overcome them through the involvement stakeholders in the mobile phone market in Cambodia. In addition, we criticize the current static efficiency-based market performance. We analyze various data including relevant government documents, operators' data, and materials from relevant websites. Furthermore, a survey was conducted with 150 people to examine the consumers' assessment on the experiences of mobile telecom services usage. The expected results will verify that the current static efficiency-based policy framework results in a stagnant market and is lacking sustainable driving force, which needs to be resolved in the dynamic perspective. Finally, we propose future policy framework for the dynamic efficiency enhancement in the market.

PurposeElectronic books (e-books) have been in the market for decades but have been unable to replace paper books. Previous studies on e-books have failed to identify significant factors affecting the adoption and diffusion of e-books. This study develops a theoretical framework to explain the adoption behavior of e-books from the perspective of user resistance.Design/methodology/approachAfter a pilot test with 50 e-book users, the research model is validated using a partial least squares structural equation modeling (PLS-SEM) technique. A web-based survey method is used to collect data from a sample of 350 people – selected from Korean e-book users and nonusers – during a week in March 2017. This study tests the reliability and validity of the integrated model of planned behavior and resistance theory and tests the hypotheses with bootstrapping resampling.FindingsThe results show that four barriers – usage, value, risk and image – cause resistance to change and users with higher resistance have lower intention to use. The moderating effect of self-efficacy between resistance to change and intention to use is confirmed. Self-efficacy interacts not only with the encouraging factors but also with resistance.Originality/valueThis study expands the understanding of users' adoption behavior of e-books by examining inhibiting factors using a novel integrated model. The findings of this research provide insights for digital product providers, especially e-book publishers, to understand why digital products have not been successful in the marketplace.
