摘要：In this paper, we use panel data to empirically analyze the stability of the export functions of LDCs for the period 1980-2004 using the nonstationary panel time series analysis. We find that the use of panel data for the region of the LDC clearly supports a cointegrating relationship. Our empirical results also show that price elasticity ranges between -0.24 and -0.34 and income elasticity ranges between 1.36 and 1.79 for the panel of LDCs
