Abstract
Clean heating renovation is important for optimizing the regional energy structure and improving the quality of the atmospheric environment in Northern China. According to survey data of 1298 rural households in the “coal-to-gas” reform in Hengshui of Hebei Province, in this paper, we construct a clean heating subsidy model which focuses on clean heating choices, the reburning rate, and the subsidy cost. The key parameters affecting farmers’ choice of clean heating, including the lifeline, classification of rural households, and gas price elasticity, are estimated. Furthermore, we simulate changes between the existing and new subsidy policies, including the impact on the welfare of rural residents. We present the following findings: (1) under the current subsidy standard, the level of gas heating lifeline in Hengshui is 700 m3, the proportion of low-gas-consumption households is approximately 47.38%, and the reburning rate ranges from 47.38% to 63.80%; (2) under a new subsidy standard which we designed to ensure that households will not reburn the coal, the optimal subsidy value is 1.23 CNY/m3, the optimal subsidy volume is 970 m3, and the total subsidy demonstrates an increase of 46.21%; and (3) the government’s subsidy standards should focus on low-income households.

Coal heating is a large contributor to the quality of the regional atmospheric environment in the Beijing–Tianjin–Hebei (BTH) Region of China [1]
Large-scale clean heating transformation is an important measure for optimizing the regional energy structure and improving the quality of the atmospheric environment [2,3]
The remaining part of this paper is organized as follows: In Section 2, we review the related literature; in Section 3. we present the construction of the subsidy model of clean heating; in Section 4, we explain the survey data and estimate three key parameters; in Section 5, we simulate the resurgence and subsidy; and in Section 6, we provide relevant suggestions on the subsidy standard
Summary
Coal heating is a large contributor to the quality of the regional atmospheric environment in the Beijing–Tianjin–Hebei (BTH) Region of China [1]. Large-scale clean heating transformation is an important measure for optimizing the regional energy structure and improving the quality of the atmospheric environment [2,3]. The effective period of government subsidy policy for clean heating is only three years. Sustainability 2021, 13, 169 the operation of clean heating facilities and encouraging users to utilize them are critical for achieving high clean heating rates [6]. In order to avoid coal reburning by farmers, it is necessary to study the standard of the clean heating subsidy after the pilot project. Heating behavior and government fiscal expenditures, in order to identify a reasonable subsidy measure that can ensure that farmers use clean energy for heating without reigniting coal and minimize the government’s fiscal expenditures. The remaining part of this paper is organized as follows: In Section 2, we review the related literature; in Section 3. we present the construction of the subsidy model of clean heating; in Section 4, we explain the survey data and estimate three key parameters; in Section 5, we simulate the resurgence and subsidy; and in Section 6, we provide relevant suggestions on the subsidy standard
