Abstract :
the purpose of this study is to investigate the long-term and short-term relationship between the impact of trade liberalization on the import of a number of inputs from the Iranian agricultural sector during the period 2009-2018 using panel data. determine To the fixed and random effects with Hausman test, the test statistic was 37.40, which is quite significant. , in estimating the model, the use of the fixed effects method was more appropriate than the random effects method. To estimate the long-term and short-term relationships of the studied variables, the model of self-explanatory integrated group panel with wide intervals (PMG) and group average (MG) was used.The results of estimating the model of the self-explanatory integrated group average panel with wide intervals and group average indicate that in the long run, the trade liberalization index has a positive effect on the import of agricultural sector inputs. The index of trade liberalization on fertilizer, chemical pesticides and agricultural seeds was calculated as -0.788, 0.17 and 0.043, respectively,
