Abstract. This paper summarizes the current main methods of heterogeneous data conversion, focuses on the necessity of establishing the data conversion specification for China's agricultural product quantity safety, as well as specifies the main designs and solutions for data conversion structure, data conversion process and data conversion format in research. Establishing a data conversion specification is a pioneering work of applying modern information technology management methods in the research areas of agricultural macroeconomic policy-making system, which plays a positive role in promoting the study of modern agricultural information system. The establishment of data conversion specification can not only improve the level of agricultural information technology research, but can also create a better research and development environment for the study of agricultural information system. Keywords: specification, agricultural product, data conversion 1.Problem Statement Chinese agricultural product quantity safety management system is an information management, analysis and decision-making system established for the study of agricultural product quantity safety. It involves large amounts of data related to agricultural product quantity safety, including the agricultural economic base data, field collection dynamic weather data, soil and crop growth data, agricultural product price data from internet, agricultural product quantity safety historical data for statistical analysis, etc., with different data sources and types. For overall system needs, to establish a unified and standardized database that can serve the agricultural system is the base for agricultural product quantity safety research. The key indicators involved in agricultural product quantity safety management system are divided into two categories. The first category is production indicators: including the arable land area, acreage, production, chemical fertilizer and pesticide use, etc. of crop production. As the agricultural product quantity safety in our study includes various consumer goods needed by human life, here the agricultural product is a broad concept, and therefore the indicators also include the breeding area,
