Towards Use of Cleaner Fuels in Urban and Rural Households in Colombia: Empirical Evidence from 2010 to 2016
利用2010至2016年哥伦比亚生活水平调查数据，研究影响家庭选择烹饪燃料的社会经济因素，发现家庭类型、教育水平和收入是关键变量，并展示了固体燃料向液化石油气和天然气转换的政策成效。
Natural Gas (NG) and Liquefied Petroleum Gas (LPG) are considered as modern fuels particularly in the urban and rural areas in developing countries. In Colombia, approximately 6.5 million people, around 13% of the population in Colombia use traditional solid fuels for cooking. Using the Colombia Living Standard Survey (CLSS) data for 2010 to 2016 in this study is investigated the mainly socioeconomic factors that influence the choice of cooking fuel in households. A Multinomial Logit Regression (MLR) model is used for empirical analysis. Results reveal several important socioeconomic variables that determine the use of fuels such as type of household, education level and household income. Moreover, results allow to show the successful implementation of the Colombian substitution energy policy, from solid to cleaner fuels such as LPG and NG along national territory. Additionally, we provide several maps to show the evolution of cooking fuel usage in rural and urban areas of Colombia from 2010 to 2016.
