Abstract: Information is the core resource of policy issue construction in the network era. Gate-keepers who occupy information structure holes are rising in importance and even can control the decision process. Gate-keeping includes nine continuous links with the progressive， synergetic and vague properties. Gate-keeping in the modern society is becoming specialized， standardized and compulsive， reducing decision-making risks while increasing potential dangers. To optimize information gate-keeping， we should conform to the trend of modernization， follow the principles of openness， prudence and inclusiveness， continuously improve the information structure and governance environment， establish the quality improvement， supervision and incentive mechanisms， and reduce the systemic risk of information gate-keeping so as to set up the multi-dimensional compound mode.

Key words: network era, policy issue construction, information gate-keeping process, multi-dimensional compound mode
