Abstract: Grain production is important role in ensuring food security. In order to support the local government’s promotion of technological innovation on the rice plantations, the paper aims to evaluate chemical fertilizer reduction and productivity improvement technology modes in a rice paddy in Huai’an Jiangsu from the perspective of its evaluating the social economic effects. Firstly, a brief introduction of the rice plantation requirements including fertilizer and soil requirements, are introduced. Secondly, briefly introduce the most important factors impact rice technological modes including (Economic benefit, Social benefit, Technical characteristics, and management) are briefly discussed. Thirdly, details of multi-correlation of social economic model based on gray correlation analysis for the promotion of organic fertilizer to replace part of the chemical fertilizer technology, followed by the special fertilizer mode, and the other three technology modes. Results show that among the final weights obtained through the gray correlation weighting method, the economic benefit index was 27.15%, followed by the social benefit index with 21.45%, the technical feature index has the highest weight of 34.24%, and the management index with the lowest weight was 17.16%. The evaluation scores of the five technical modes, the ranking of their comprehensive evaluation score from high to low is mode 2 (0.305925) > mode 1 (0.240125) > mode 4 (0.179925) > mode 5 (0.1447) > mode 3 (0.129825). The application of mode 2, that is, the organic substitution of partial fertilizer technology, ranks the first among the five technical modes in the comprehensive evaluation; therefore, it is worthy of prioritization.
