农产品地理标志产业集群显性效益分析——基于河南地理标志产业集群的数理解释Analysis on the explicit benefit of the industry clusters of agriculture Geographical indications: Based on the quantitative case study of Henan Province

地理标志产品因其生产的地域性、品质的独特性而拥有很高的知名度，具有很高的无形价值即“影”价值，有时这一“影”价值远远超过产品自身的“形”价值。文章基于对农业经营方式和组织方式改变的宏观经济效益的分析，以河南地理标志产业集群为背景，用C-D函数模型作为基本框架，通过构建新数理模型对地理标志产业集群经营的显性经济效益（农业GDP的增长、农民收入增长等）进行定量测算，以判定该数理分析的适用性和可行性。The Products with geographical indication are usually of great recognition for special locality and unique qualitiy, which leads to high invisible values, and sometimes, the invisible values are higher than the visible values. Based on the benefit analysis of changes in agricultural management patterns and agriculture organizing patterns, the research brought forward a basic framework with C-D function model and quantitatively messured the expelicit economic benefits (e.g., agricultural GDP growth, farmers’ income increase) of the industry clusters of agriculture geographical indications in Henan Province through constructing mathematical models. The results of the case study proved the feasibility and applicability of the quantitive research.
