The Saihanba Forest Farm, a leading planted forest farm, is one of the essential ecosystem service providers for the Beijing–Tianjin–Hebei region in China. Its efforts in afforestation and landscape restoration have been recognized with the award of the Champions of the Earth from the United Nations. However, the Saihanba Forest Farm is facing the challenges of less income resulting from less commercial cutting since it has to prioritize providing ecosystem services such as water conservation, wind prevention, sand fixation, and so on, instead of timber. It is crucial to understand providers’ attitudes toward ecosystem service provision and willingness to accept payment, as it might affect the quantity and quality of ecosystem service provision in the future. In this study, the contingent valuation method was applied to measure the willingness to accept payment for the economic losses incurred due to providing ecosystem services by cutting less wood. A questionnaire survey was conducted among the staff of the Saihanba Forest Farm. A double-hurdle regression model was used to analyze the influencing factors of the willingness to accept payment, with the validation via a Tobit model. The results showed that the Saihanba Forest Farm was willing to accept a payment of CNY 9800.84 (USD 1407.24) per hectare per year for providing ecosystem services to enhance social welfare. The factors, including basic sociodemographic characteristics, attitudes toward conservation activities, and awareness on the concept of payment for ecosystem services, significantly influenced their willingness to accept payment.
