一、预测性信息的来源应具有权威性。最好是选自省市统计局城市调查队或农村调查队的报告或是选自综合部门、占有重要地位的大市场的报告,如汽车工业总公司、机械工业总公司、郑州粮食批发交易市场等等。 二、选编预测性信息应注明出处。注明出处一来是尊重别人的智力劳动,二来可以避免因信息失实带来的麻烦。 三、采写预测性信息要避免直观地运用信息材料。预测是对不确定的未来发展所作的分析和表述,
First, the source of predictive information should be authoritative. It is best to choose from the reports of the Urban Surveys or Rural Surveys of the Provincial Bureau of Statistics or the large markets that have an important position in the general department, such as the Automobile Industry Corporation, Machinery Industry Corporation, Zhengzhou Grain Wholesale Market and many more. Second, the selection of predictive information should indicate the source. To indicate the source is to respect other people’s intellectual work, and secondly, to avoid the trouble caused by the information false. Third, to write predictive information to avoid the intuitive use of information materials. Forecasting is the analysis and formulation of uncertain future developments.
