The innovation and promotion of the rural collective economic development model is an important starting point for comprehensively promoting the rural revitalization strategy, and it plays a role in promoting the economic transformation of China’s rural areas. However, in the process of the government-led new rural collective economic model promotion, many villages have fallen into development difficulties after model-learning. Therefore, it is worth reflecting on why a policy model that has been verified in the field and accepted by the promotion target still loses its effect? Contrary to the interpretive approach of realism, based on a long-term survey and multi-case comparison of County J in southern Jiangsu, this study takes narrative construction as an analytical perspective, and attempts to present the interactive situation of model promotion from local dimensions such as technology-emotion, problem-opportunity, consensus-decision, which reveals the narrative means of model promotion and organizational decisions under the influence of the former. The research finds that the failure begins with the rational deviation in the decision-making stage, and the cognition and decision-making of policy objects are always in a situation of being constructed by narrative. The reason is that the preference and ability of bureaucracy drives value-oriented narrative production. Promotional narrative constructs shared concepts and compromise decisions through attention-grabbing, opposing choices, and emotional engagement, and consent comes from manufacturing. And organizational decision-making is plagued by information distortion, internal and external contradictions, and neglect of local factors. The study further interprets the “narrative rationality” of organizational decision-making, and examines the promotion process of various “policy models” in rural areas.
