Scientific and reasonable survey system design is the premise to ensure the smooth development of various investigation work and the quality of survey data. The advent of the era of big data objectively requires us to carry out corresponding reform in the statistical investigation system, so as to fully tap the potential of big data in government statistics. This paper puts forward a series of reform ideas for China's government statistical survey system from the perspectives of ideology, mode of thinking, work style, survey methods, survey means, survey content, survey items, survey indicators, data release and follow-up analysis. This system solves all kinds of problems existing in the current survey system, combines the traditional survey methods with the new electronic recording data, integrates and utilizes all kinds of big data resources. The goal is to produce all kinds of macro time series data and micro vertical data more accurately, timely, comprehensively and continuously, so as to promote the reform and development of China's statistical management system.
