The EKC relationship between GDP and greenhouse gas (GHG) emissions shows an inverted U-shape based on the GHG emissions accounting data in Heilongjiang province from 2001 to 2015, and the curve is expected to reach inflection point in 2019. The results of average annual emission reduction of 4 paths by partial least-squares regression model are as follows: the reduction of energy consumption per unit GDP, the adjustment of economic structure, the growth of per capita GDP, the change of trade structure. The dynamic impact effects for corresponding impulse response functions are fluctuating emission increase, convergent emission reduction, divergent emission reduction, and transformational emission effect. The paths order of promoting GHG emission reduction in Heilongjiang province is to control fossil energy consumption, optimize economic structure, develop low-carbon economy and adjust trade structure.

Key words: EKC (Environmental Kuznets Curve), Emissions reduction paths, Greenhouse gas emissions per unit of GDP, Impulse response function
