To reduce the carbon emission intensity of resource-based cities and strengthen the sustainable development of these cities, firstly, blockchain technology is analyzed. Secondly, the development of the digital economy is discussed in digital resource-based cities. Finally, according to blockchain technology, a model of carbon emissions trading in the digital economy is designed, and the specific impact of the digital economy on carbon emissions trading is studied according to the model. The research results show that the mean value of the development index of the digital economy () is -0.0168, the maximum value is 4.2560, the minimum value is -1.3429, and the standard deviation is 0.9572, indicating that the quality of digital economy development varies greatly among different regions. And according to the results of the digital model, it is found that the regression coefficient of the variable is significantly negative at the 1% level, showing that the digital economy will obviously suppress the carbon emission intensity of cities. After replacing the explained variables, the coefficient of the digital economy is still significantly negative. It indicates that the development of the digital economy can effectively suppress the carbon emission intensity of urban. Therefore, the designed model of carbon emissions trading under the blockchain technology can not only provide a secure platform for carbon emissions trading but also provide more comprehensive trading reference information for carbon emissions trading. It provides technical support for reducing the carbon emission intensity of resource-based cities and also contributes to the development of resource-based cities.
为降低资源型城市碳排放强度，增强城市可持续发展能力，首先分析区块链技术，其次探讨数字资源型城市的数字经济发展，最后根据区块链技术设计数字经济下的碳交易模型，并根据模型研究数字经济对碳交易的具体影响。研究结果表明，数字经济发展指数的均值为-0.0168，最大值为 4.2560，最小值为-1.3429，标准差为 0.9572，表明不同地区数字经济发展质量差异较大。并且根据数字模型的结果发现，变量的回归系数在 1%水平上显著为负，表明数字经济将显著抑制城市的碳排放强度。在替换被解释变量后，数字经济的系数仍然显著为负，表明数字经济的发展可以有效抑制城市的碳排放强度。因此，设计的区块链技术下的碳交易模型不仅可以为碳交易提供安全的平台，还可以为碳交易提供更全面的交易参考信息，为降低资源型城市碳排放强度提供技术支持，也为资源型城市的发展做出贡献。
