Nonlinear autoregressive distributed lag model(NARDL)is used to explore the asymmetric impact of linear low density polyethylene(LLDPE)price in global market on the price in Chinese market through selecting the spot LLDPE prices in the Middle East,Southeast Asia,the United States and China from January 2010 to December 2023 for analysis.Empirical results show that LLDPE in China relies more on LLDPE prices in the Middle East market than those in the United States and Southeast Asia markets.Meanwhile,the LLDPE prices in Southeast Asia,the Middle East and the United States of America conduct asymmetrically onto China's LLDPE prices,and showing heterogeneous characteristics in asymmetrical conduction degree and speed.In which,the conduction degree and speed of LLDPE price decline from the United States of America market are greater than those of LLDPE price increase;The price conduction from Southeast Asia market also reflects negative asymmetry in the conduction degree,but does not reflect significant asymmetry in the conduction speed;The price conduction degree of LLDPE price increase from the Middle East market is larger than that of price decline,but there is smaller difference in the conduction speed of price increase and decline.
