The conclusion is that the path of Nanjie's institutional change is the outcome of the coevolution, say, competition, constraints, enforcement and transformation between the state and market; the coevolution have three dimensions: benefit, legitimacy and ideology; the path and outcome of institutional change in the process of coevolution are shaped by both the dual process of modernization and marketization in China's social transformation and the path dependence and cultural lag in China's incremental reform strategy: on the one hand, as historical conditions, the proceeding and logic of China's modernization constraint the state and market's institutional choices; on the other hand, under the interplay between the path dependence and cultural lag, the interaction between the state and market can produce various complex combinations, therefore various institutional landscape, even "institutional paradox".

本文认为，高度政治化、高度集体化的南街村体制是国家与市场互动演化，即国家与市场之间相互竞争、制约、强化和改变的结果；国家与市场之间的互动演化有利益、合法性和意识形态等三个维度，而互动演化所造成的制度变迁轨迹和结果则同时受中国社会转型中的现代化进程和市场化进程，以及渐进式改革中的路径依赖和文化堕距的影响：一方面，现代化进程作为一种共同的历史条件制约着国家和市场各自在互动过程中的制度选择；另一方面，在路径依赖和文化堕距的交互作用下，国家与市场之间的互动会形成多种复杂的、犬牙交错的组合，从而塑造出千姿百态的制度景象甚至"悖论"。
