Bài báo này được thực hiện nhằm phân tách các yếu tố ảnh hưởng đến sự thay đổi cường độ năng lượng của các hoạt động dịch vụ vận tải giai đoạn 2007-2012 và 2012-2019 sử dụng kỹ thuật phân tách phân rã chỉ số (LMDI). | Journal of Science and Transport Technology University of Transport Technology Decomposition analysis of factors affecting the energy intensity change for transport service activities in Vietnam Pham Thi Hue University of Transport Technology 54 Trieu Khuc Thanh Xuan Ha Noi Vietnam Article info Abstract Transport service activities have an increasingly important contribution Type of article to the economic and social development of Vietnam. However these activities Original research cause great energy consumption affecting energy security and environmental paper quality. Studies of their energy intensity have also been carried out in the past the decomposition analysis of expansion effect factors for Corresponding transport services is still limited. This paper s purpose is to decompose factors author affecting energy intensity change of transport service activities in the period 2007- E-mail address 2012 and 2012-2019 using Logarithmic Mean Divisia Index LMDI method. huept@ These two periods are analysed uponoriginal Input-Output IO table published in 2007 and 2012. Besides IO table 2019 is updated and used to survey energy Received intensity change in recent years. The energy intensity is decomposed with three November 23 2021 factors including effects of changes in economic activity effects of energy Accepted consumption and effects of final demand. The results show that most of the three December 14 2021 influencing factors cause an increase in energy intensity. This result is the basis Published for proposing solutions to improve the factors affecting the energy intensity December 20 2021 increase for transport service activities in Vietnam.
