摘要 通过构建协调博弈框架,对城镇化进程中参与博弈的地方政府和农民主体的偏好、相互间的策略互动和一致性行为进行分析。分析了导致协调失败的因素:地方政府利用自身的行政权力强制推进城镇化进程,博弈参与人之间互信机制的缺失以及博弈参与人预期合作的成本过大等。在此基础上提出了解决协调失败、实现新型城镇化良性发展的对策。

Abstract Based on the framework of coordination games, the paper describes the preference, strategic interaction, and consistent behaviors of local governments and the farmers, both of which are participants of the coordination game. The paper analyzes the factors that led to the failure of coordination, such as local governments promote urbanization forcibly using its executive power, the lack of expectation on cooperation and the mutual trust mechanism between game participants is difficult to establish, the larger expected cost of cooperation lead to the consequence that the net gain of cooperation is less than that of noncooperation, leading to coordination failure. According to the above analysis, several suggestions about how to solve coordination failure were put forward in order to promote new urbanization.

在政府的推動下,我国城镇化水平不断提高,2011年城镇化率历史性突破50%。然而,在政绩和财政收入激机制励下,地方政府可能会违反客观规律,强制推进城镇化。在这一过程中,农民主体被排除在城镇化进程之外,无法分享城镇化所带来的收益,由此产生的各种社会问题[1],影响城镇化的健康发展。积极稳妥推进城镇化,完善城镇化健康发展机制是实现城乡一体化发展的关键所在。笔者试图通过构建协调博弈模型,探讨城镇化过程中地方政府与农民主体的策略选择以及合作的激励机制,最终提出新型城镇化健康发展的对策。
1 以地方政府和农民主体为参与人的协调博弈
1.1 模型的基本假设
基于相关文献,构建2×2对称博弈结构。假设博弈参与人为两个(i=1,2),即农民主体和地方政府。参与人i的策略变量为ei∈[0,E],E代表参与人的行动边界。策略变量为农民主体和地方政府的活动水平或努力水平,在模型中简化为∈Si和e∈Si。……
