Management strategy of carbon sequestration forest under carbon sequestration price insurance
【Objective】 Under the background of a “dual carbon” objective, the optimal management strategy of carbon sink forest under carbon sink price insurance was studied with the aim of providing a reference for decision-making of carbon sink forest management.【Method】 Taking the carbon sink price insurance contract composed of forest operators and insurance companies as the research object, the conditional value at risk (CVaR) measurement criterion and Stackelberg game model were used to study the management strategy of carbon sink under carbon sink price insurance.【Result】When the target price of carbon sink in carbon sink price insurance was low, the increase of risk avoidance degree of forest operators would reduce the planting scale of carbon sink forests, the total carbon sink, and insurance cost, but would increase the carbon sink per unit area. In contrast, when the target price of carbon sink in carbon sink price insurance was high, the planting scale of carbon sink forests, the total amount of carbon sink, and the insurance cost were not affected by the risk avoidance degree of forest enterprises. The results also showed that increases in the target price of carbon sink and the subsidy rate of carbon sink price insurance could increase the planting scale and the total carbon sink but reduced the carbon sink per unit area. In addition, if the government provided the same amount of premium subsidies to forest enterprises and insurance companies respectively, government subsidies for insurance companies could promote the growth of planting scale and total carbon sink more than subsidies for forest enterprises, but the marginal efficiency of both subsidy methods was decreasing. 【Conclusion】Forest enterprises can reduce the impact of their risk avoidance behavior on carbon sequestration forest management by purchasing carbon sequestration price insurance. When forest enterprises and insurance companies agree on the target price of carbon sink in carbon sink price insurance, they should set the target price of carbon sink within a reasonable range. The government can combine subsidies to forest enterprises and insurance companies to improve the quality and supply of carbon sinks.
