Abstract: The society has entered into a highly complex and uncertain age under the influence of postindustrialization and postnormal science. Meanwhile， the influx of large amounts of information in a short time has posed a huge challenge to the governments administrative decisionmaking efficacy. The ability of decision making within a reasonable time is affected by the governments administrative decisionmaking time limit as well as the timeliness of their policy outputs. Time， in the form of time limit and time pressure， plays an important role in administrative decision making. The fluctuation of decisionmakers cognitive emotions may affect information gathering， program choosing and the validity of decision assessment， which consequently influences the level and ability of the governments administrative decision making. Therefore， the administrative staff need to integrate learning into decision making， seize appropriate opportunities in the process of decision retrospect and prospect， and have control over time limit and time pressure. Only in this way could the efficacy of the governments administrative decision making be improved.

Key words: time limit, time pressure, administrative decision, decisionmaking efficacy
