Research On The Causes And Behaviors Of Nail Households In The Process Of Land Expropriation And Demolition Based On Dynamic Game Theory

With the rapid development of urbanization in China,land acquisition and demolition has gradually become a social issue that has received wide public attention,and the resulting social conflicts have been commonplace.The social consequences caused by the nail household incidents are the most serious,and have also attracted the most attention of the government and the public.while causing huge economic losses,it will also seriously affect the harmony and stability of society.Now it has become a restrictive factor in the process of urbanization development in China.At present,previous studies have not yet provided definite conclusions on the internal mechanism of nail household behavior;In practice,most land acquisition and demolition behavior lacks the pertinence to solve the problem,resulting in the waste of resources.From this point of view,explaining the internal mechanism of land expropriation and demolition from a micro perspective is the key to resolve the contradictions and conflicts between land expropriation and demolition which is also a theory urgently needed to improve.The purpose of this study is to construct a mechanism that can explain the choice of land expropriation and demolition behavior in China,and to explore the micro-mechanism of the evolution of game behavior of different types of expropriated and demolished households from the root causes.Based on the analysis of the main influencing factors of behavior choice,this study establishes a relatively complete classification system for the requisitioned and demolished households,and classifies the requisitioned and demolished households.On the basis of game theory,the whole process of land expropriation and demolition is comprehensively analyzed.The game path and behavior choice of land expropriation and demolition are systematically analyzed from the vertical direction,and the connotation of economic utility and decision-making behavior of the party being expropriated and demolished at each stage is emphatically analyzed from the horizontal direction.It focuses on the analysis of action logic and strategy selection of different types of requisitioned and demolished households,and constructs multi-stage dynamic game model of different types of requisitioned and demolished households by eliminating disadvantagestrategy and game tree method.Then,from the perspective of information economics,this paper focuses on the mechanism of information on the behavior choice of the expropriated and demolished households,trying to turn the game of interests of land expropriation and demolition to another direction-Information game,and concludes that the result of the game of land expropriation and demolition is determined by the cost-benefit structure of the expropriated and demolished party and the grasp degree of game information.Finally,case analysis method is used to validate the practicability of the multi-stage dynamic game model of the requisitioned and disassembled party.Through the above layers of anatomy,the main conclusions and suggestions are as follows:(1)The four classification criteria proposed in this paper are proved to be reasonable.(2)Eight types of requisitioned households can basically reflect the actual situation of the requisitioned households in the process of land requisition and demolition.Based on the dynamic game analysis of the classification of the requisitioned households,the logic of action of different types of relocated households is revealed,and the causes of nail households are well explained.Case studies further support the conclusions of the game analysis.(3)The requisitioner can accurately assess the risk of land requisition and demolition only on the basis of fully grasping the information of the object being demolished,which at the same time can formulate a targeted requisition policy.Based on the four classification criteria proposed in this paper,it is more conducive to quickly and accurately judge the type of households being requisitioned,and to improve the efficiency of land requisition and demolition.(4)Cost and net income should be regulated from two aspects of information quantity and mechanism design in order to change the behavior choice of the party requisitioned and demolished,and reduce the action conflict in land requisition and demolition.
