Đánh giá hiệu quả sinh thái tại Việt Nam giai đoạn 1999-2017 bằng phương pháp phân tách và tiếp cận chỉ số hiệu quả Malmquist DEA
Nội dung chính của bài viết
The relationship between economic development accompanied by environmental friendliness, and ecological balance is the top concern of the strategic planners of sustainable development in each country. Based on Tapio decoupling analysis and measure productivity index from Malmquist - Data Envelopment Analysis Vietnam’s eco-efficiency during 1990-2017 was investigated. The outstanding results are as follows: Since 2004 onwards, the changes have been recorded in the relationship between affluence and the environment - the ecosystem under the gradual diversity of degrees: expansive decoupling; weak decoupling; expansive coupling, and strong decoupling under Tapio decoupling analysis. At the same time, the Malmquist productivity index has improved slightly with 4.4% over 28 studied years. It shows that Vietnam gradually approaching and implementing strategies for improving the quality of the environment and the ecosystem. However, there is still an upward trend in the amount of emission with an annual emission growth rate of 43.4% while the economic development rate has not shown balance and similarities. Therefore, the reform of management policy, scientific strategy, and updating of technology system should be considered and implemented synchronously to maintain this change and promote the development in a more positive direction.
