Abstract
This research aimed to study the level of accessibility to information, knowledge, perception of different characteristics of innovations and their adoptions, including a study of the relationship between the factors mentioned above and the innovation adoption for energy conservation in private cars for people in Bangkok. The sample was selected from the population age between 20–60 years old by using stratified three-stage random sampling. The data collection was conducted by using questionnaires and the analysis was undertaken by means of descriptive statistics and logistic regression to analyze the relationship between the factors and innovation adoption together with CHAID in order to analyze the relative importance of factors in relation to innovation adoption. According to 400 respondents, the study found that in terms of energy situations and problems together with energy conservation innovation issues, most people had high accessibility to this information and about half of them had moderate knowledge; for the social support from government and private sectors issue, about half of them also had high accessibility to this information but mostly with low knowledge; regarding to the perception of different characteristics of innovations, it was indicated that most of the people had moderate perception of risk, comparative advantage and complexity, more than half also had moderate perception of compatibility. Concerning with energy conservation innovation adoption in private cars, both at present and in the future from four categories; gasohol, biodiesel, natural gas and other potential innovations in the future, it was shown that most of the people adopted at least one category in the future. Furthermore, logistic regression analysis showed that there were three factors affecting the innovation adoption, both at present and in the future; i.e. gender, private car user and perception of innovation characteristics in terms of comparative advantage. The result indicated that males tended to adopt innovations, both at present and in the future, 2.008 and 2.292 times more than females respectively; private car users tended to adopt innovations, both at present and in the future, 3.423 and 1.875 times more than non car users respectively; and the perception of innovations in terms of their comparative advantage had positive relationship to innovation adoption, both at present and in the future. The probability to adopt innovation should increase by 5.9% and 7.9% respectively if the comparative advantage perception score increased by 1 unit. On the other hand, CHAID analysis showed that the first important factor to be considered in relation to innovation adoption at present was private car use. Car users tended to adopt innovations more than non car users. The next factor was the perception of innovations in terms of comparative advantage. If this perception score increased, it would affect more adoption of innovations. Whereas, the first important factor related to the innovation adoption in the future was gender. Males tended to adopt innovations more than females. The private car use by males was the next issue for consideration. It was shown that males using private cars tended to adopt innovation more than non car users which was quite different from females as it was indicated that if the perception score increased, so did the innovation adoption as a consequence. The study results recommended the enhancement of aggressive innovation promotion that was focused on comparative advantage concerning personal and public benefits in order to increase the innovation adoption in females as well as non private car users. Furthermore, there were obstacles of innovation adoption which arose from either the consumers themselves or different social context that might cause damages to the economy, society, environment and public health as a whole, the government should have an integrated supervision system to convince people to adopt more energy conservation innovations, both at present and in the future for the benefits of the people and the country as a whole.
