A Study on the Influencing Factors on the Economic Performances of the Waste-to-Energy Companies in Korea: Focusing on the Mediating Effects of the Government Policies
Journal of Korean Society of Environmental Engineers
This study is analyzing whether there are mediating effects of government policies between inputs and economic performances of Korean waste-to-energy (WTE) companies. The independent variables are set as the input factors of the WTE companies and the dependent variables are defined as the economic performances of the WTE companies. In addition, the mediating variables are defined as the government policies. In order to analyze the mediating effects of the policies, we conducted a questionnaire
... ed a questionnaire survey on Korean WTE companies and the mediating analysis using the PROCESS Macro proposed by Hayes (2013). As results of the analysis, the increase in the inputs of the Korean WTE companies has been found to affect the increase of the performances through the government policies. In addition, as a result of comparing the mediating effects by detailed policies, it has been found that the mediating effect was greater in the order of RPS system > the price variation of electricity > the obligation of greenhouse gas reduction. Based on the results of this analysis, it is necessary to establish industrial revitalization factors to enhance the efficiency of the RPS system in view of the large mediating effect of the RPS system on Korean WTE companies.
