Abstract:

In order to reveal the coupling relationships among space exploitation, economy development and environment evolution, we introduce the concept of coupling degree and build the evaluation index system which includes 36 indicators embodying these three aspects. By using variable coefficient method, trend surface model and multiple regression model, we analyze the characteristics and mechanism of the differentiation of coupling degrees among space exploitation, economy development, environment evolution in Harbin-Dalian Giant Urban Belt during 2000-2014. The results show that: 1) The coupling degrees of space exploitation, economy development and environment evolution have demonstrated different levels of imbalance since 2000, and the degrees in west area are higher than those in east area. Even so, the coupling degrees are overall rising. The coupling degrees in Harbin-Changchun sub-district, the central and southern Liaoning Province sub-district and Harbin-Dalian Giant Urban Belt rose at the beginning, then reduced, which shows a good trend on the whole. 2) Government investment had a significant effect on the differentiation of coupling degree in Harbin-Dalian Giant Urban Belt in 2000. Science and technology input intensity and capital input intensity are the leading factors in 2007 and 2014. The differences of urban development energy level and coupling degree among cities were consistent in 2007. 3) Under the influence of science and technology input, government input and capital input, in Harbin-Changchun sub-district, the coupling degrees among space exploitation, economy development and environment evolution show significant differences, but in central and southern Liaoning Province sub-district, the influencing factors of differentiations of coupling degree changed gradually from human capital efficiency and administrative rank to capital input intensity.

Key words: space exploitation, economy development, environment evolution, differentiation mechanism of coupling degree, Harbin-Dalian Giant Urban Belt
