Research On The Improvement Effect Of Blockchain Technology On The Financing Dilemma Of Family Farms In China ——Based On Evolutionary Game Theory

The issue of "agriculture,rural areas and farmers" is a significant problem related to China's national economy and people's livelihood,and the key to the issue of "agriculture,rural areas and farmers" is food security,which should attract key attention.At present,family farm has become the main representative form of China's new agricultural management subject,which is very important to ensure China's food security.Central Government Document No.1 of 2022 mentioned supporting family farms to grow more grain and grow better grain.Since the 2013 central document No.1 mentioned the development of family farms for the first time,the number of family farms in China has been growing rapidly,the scale has been expanding day by day,and the income has remained stable.However,there are still many restrictive factors in the development of family farms in China,the most important one is the financing dilemma of family farms.Based on the analysis of the superficial reasons,this paper concludes that the root cause of the financing difficulties of family farms is the Information asymmetry between family farms and financial institutions,Although Chinese experts and scholars have put forward many institutional advice,these suggestions have not fully improved it.Therefore,it is necessary to introduce the innovation of financial technology,namely blockchain technology,to improve it.Based on this,this paper analyzes the impact and improvement of blockchain technology on the financing predicament of family farms in China,and introduces the cases of applying blockchain technology to the financing of small and medium-sized agricultural enterprises,in order to improve the information asymmetry between family farms and financial institutions,so as to solve the financing difficulties of family farms,so that our family farms can be better developed.This paper mainly uses the evolutionary game method,by introducing the block chain technology into the family farm financing activities,this paper constructs two evolutionary game models based on blockchain technology under the condition of existence or non-existence of agricultural financial platform and carries out simulation,and compares and analyzes the simulation results,the function of blockchain technology to the financing predicament of family farm in our country is obtained and the relevant policy suggestions are put forward.Firstly,this paper introduces the current situation of the financing dilemma of family farms in China,analyzes the surface causes of the financing dilemma of family farms,summarizes its root causes,and leads to the conclusion that blockchain technology can improve the financing dilemma of family farms;Secondly,it explains the applicability of blockchain technology in the financing dilemma of family farms in China,which lays a theoretical and practical foundation for its application in family farm financing;Then,by comparing and analyzing the simulation results of evolutionary game model,we can get the practical effect of blockchain technology on family farm financing;Finally,it briefly introduces the relevant cases of blockchain technology to solve the financing difficulties of small,medium-sized and micro agricultural enterprises,so as to provide reference for its application in family farm financing activities in China.The study shows that in the current financing environment,when the cost of family farm's performance is greater than the loss of non-performance,the financial institution will not grant the loan,whether the family farm has the intention of performance or not;After establishing the agricultural financial platform based on blockchain technology,when the mutual trust income between the family farm and the financial institution is greater than the opportunity income of the financial institution,the financial institution will choose the loan,and as the mutual trust income gradually increases,in the end,the family farm chose to honor the contract,and the financial institution chose to grant the loan,thus achieving a win-win situation.According to the research results,this paper puts forward some suggestions to improve the financing predicament of family farms: Firstly,the government should establish an agricultural financial platform based on blockchain technology,and set up three subordinate platforms under the agricultural financial platform,they are the big data platform of family farm,the credit platform of family farm and the platform of rural financial system.Second,the government or other supporting agencies are required to monitor the use of the funds after family farm financing to prevent it from changing the use of funds at will.Finally,the platform should establish a data security unit and take appropriate measures to ensure data security and prevent data leakage.
