Abstract:

With the emergence of new ‘The Northeast China Phenomenon’, the transformation and sustainable development of the Northeast China were highlighted, and sustainable livelihood security needed to be improved urgently. Based on the framework of sustainable livelihood security analysis, the study constructed a evaluation system of sustainable livelihood security including 27 indicators in Northeast China by taking the 37 prefecture level cities of the Northeast China as the research object from 2003 to 2015. By using GRA-TOPSIS model, the study had a comprehensive measure of sustainable livelihoods security in the Northeast China. Based on spatial autocorrelation method, geographical detector and obstacle degree model, the study not only revealed spatio-temporal evolution of sustainable livelihood security, but also analyzed the causes of spatial differentiation and the diagnosis of obstacle factors in the Northeast China since 2003. The result showed that: 1) Sustainable livelihood security index (SLSI) in the Northeast China was on the low level as a whole, and the characteristics of spatial differentiation were obvious, but its regional difference reduced gradually in recent years. 2) The spatial agglomeration of sustainable livelihoods security in the Northeast China presented significantly, and the hot spots and sub hot spots showed the main area including the Shenyang-Dalian and Harbin-Changchun groups; the sub cold area and cold area were marginally distributed in less-developed areas, including the eastern Inner Mongolia Autonomous Region, the northern Heilongjiang Province and the southern Jilin Province. 3) Industrialization level, economic output, wage, emission intensity of sulfur dioxide and investment intensity are the main influencing factors of sustainable livelihood security in Northeast china. 4) The supporting capacity of resources and environment and economic productivity are the two short boards restricting the sustainable livelihood security improvement in Northeast China, and the most dominant type of economic efficiency is the most widely distributed area. Finally, this study put forward the factors of regional policy and system into the framework of sustainable livelihood security analysis.

Key words: sustainable livelihood security, spatial resistance model, Northeast China
