Research On Ecological Construction Of Characteristic Agricultural Products Supply Chain Based On Value Sharing Path In Guilin

With its unique natural endowment,Guilin has been selected as the advantageous area of agricultural products with Chinese characteristics for many times.Guilin citrus,kumquat,persimmon and Siraitia grosvenorii,with prefecture level cities as units,rank first in terms of area and output in China.The realization of the full supply chain value of characteristic agricultural products is of great significance to Guilin’s rural economy.For example,citrus and Siraitia grosvenorii are the key industrial support for Guilin’s rural residents to get rid of poverty and become rich.However,the high homogeneity of product categories leads to vicious competition among growers in the sales game,shoddy goods are replaced by good ones,buyers depress grades and prices,passive,weak or even missing control of the terminal market,and the value decomposition of the supply chain system is unreasonable,With low adaptability,we need to take value sharing as the path to build a supply chain ecology to solve the above problems.Therefore,based on the perspective of value sharing,this paper takes Guilin characteristic agricultural products supply chain as the research object,uses QCA to analyze the influence mechanism of Guilin low adaptability characteristic agricultural products supply chain,and obtains five formation paths of Guilin low adaptability characteristic agricultural products supply chain: PQ × AI × TM、AI × ～TM × MC、PQ × AI × ～BI、AI × BI、PQ × ～AI × TM × MC.Then,the differential game theory is used to construct the tripartite differential game model of the path behavior subject(characteristic agricultural product grower,characteristic agricultural product purchaser and characteristic agricultural product association),in which the value sharing contract is added,and the model is solved by using Behrman dynamic optimization and Ponzi maximum theory to obtain centralized decision-making,decentralized decision-making Based on the equilibrium solution and equilibrium conditions of value sharing path decision.The results show that:(1)the investment efforts of characteristic agricultural products growers,characteristic agricultural products purchasers and characteristic agricultural products associations under the value sharing path decision-making scenario are higher than those under the centralized decision-making scenario;The investment effort of the three parties in the centralized decision-making scenario is greater than that in the decentralized decision-making scenario.It shows that under the path of value sharing,the three parties in the supply chain of characteristic agricultural products are willing to make more investment and efforts on the "characteristic" reputation of characteristic agricultural products.(2)The comprehensive value of characteristic agricultural products growers,characteristic agricultural products purchasers and characteristic agricultural products associations based on the value sharing path decision-making situation is greater than that of the three parties under the centralized decision-making situation;The three-party comprehensive value under centralized decision-making is greater than that under decentralized decision-making.Finally,based on the previous analysis and demonstration,this paper constructs the supply chain ecology of Guilin characteristic agricultural products,and puts forward some management strategies for the development of Guilin characteristic agricultural products supply chain.
