Based on the propensity score weighting method ,this paper constructs a Horvitz‐Thompson estimator of the web survey population parameters which is an unbiased estimator ,discusses the variance of Horvitz‐Thompson estimator ,analyzes the sources of variance of the population parameters estimator by using the complete sample which is imputed missing data of non‐response unit in the web survey .We have put forward new theory and method in the aspect of parameter estimation of web‐based survey .
