| Abstract: | This paper prosed a kind of varying coefficient simultaneous equation models in the random design case.estimated the varying coefficient of the models,and studied the large sample properties of estimator by the local linear GMM with Variable Bandwidth.The large sample properties of estimator were proved by using laws of large numbers and central limit theorems in probability.Local linear estimators by GMM with Variable Bandwidth has two properties:consistency and asymptotic normality. |

| Keywords: | varying coefficient local linear GMM with variable bandwidth consistency asymptotic normality |
