Impact of Industrial Structure Change on Ecological Footprint in Underdeveloped Areas:A Case of Yunnan Province
以云南省为例，利用生态足迹和VAR模型分析三次产业发展对生态足迹的动态影响，发现短期内第一产业影响最大，长期看第三产业有助于减少生态足迹。
This paper takes Yunnan province as an example.It comprehensively used ecological footprint,VAR model and the generalized impulse response function,etc.Based on the analysis of the three industrial developments and the dynamic changes of the ecological footprint,it made a further analysis about the influence of values of three industrial products to the ecological footprint.The results showed that:(1) In the past 20 years,the output value of the three industries showed faster growth in Yunnan,at the same time,its total ecological footprint also showed year-on-year growth trends.From the contribution of the elements of ecological footprint,the ecological footprint of arable land,grassland and fossil energy land had a larger contribution to the total ecological footprint,however,they showed a slower growth;on the contrary,the ecological footprint of forest land,waters and construction land had a smaller contribution to the total ecological footprint,but they showed a faster growth.The faster development of the three industries had a greater impact on the ecological footprint and its elements in Yunnan.(2) In the short term,the order of the influence degree from three industrial developments to ecological footprint,followed by the primary industry,secondary and tertiary industry.Besides,the influence of three industries to the ecological footprint was positively relevant.However,in the long term,the development of the tertiary industry have would be contributed to reduce regional ecological footprint.Based on all of the above,to promote the scientific,sustained and healthful development of low-power and low-carbon economy,and achieve coordinated and sustainable development of regional economy and society and resources and environment,we should vigorously develop the plateau modern agriculture and intensive agriculture,and establish the export-oriented industrial park groups with regional characteristic,so that the development of the tertiary industry can be promoted which is mainly based on the tourism and service industry.We should also apply to the state for ecological compensation and industrial compensation policy.
