京津冀地区是全国重要的高新技术产地与重工业基地，在前期发展中，由于过度追求经济效益而导致生态失衡，从而引发环境问题，影响农业生产，引起农业生产效率的下降。为了研究京津冀地区绿色金融的发展水平以及其对农业发展的作用，文章通过建立绿色金融指标体系，运用熵值法对京津冀绿色金融发展水平进行测算分析；基于DEA-Malmquist模型分析京津冀地区农业碳排放效率；将二者进行耦合协调度分析，展开对京津冀3地的区域差异性分析。在研究中发现，京津冀地区绿色金融发展尚且处在初级阶段，仍有较大发展空间；京津冀地区农业碳排放效率呈良性，京津两市农业碳排放技术效率有待提升；绿色金融发展水平与农业碳排放效率的耦合水平较低，需要不断提升二者的协调性。本文针对上述问题给出了以下建议：加快构建绿色金融市场体系；推动六大高耗能产业向绿色低碳发展型转变；重视金融人才与绿色金融发展相结合；北京市发挥带头作用，为天津市和河北省提供人才和技术支持，带动天津市和河北省不断发展；天津市应注重农业技术的更新，不断提高农业发展水平，实现高效率的农业生产；河北省应从多方面改进农业生产方式，提高农业技术发展水平，提升农业碳排放效率，以促进京津冀地区绿色金融的发展，保证农业低碳发展。

The Beijing-Tianjin-Hebei region is an important high-tech producing area and heavy industrial base in China. In the early stage of development, the ecological imbalance caused by excessive pursuit of economic benefits has led to environmental problems, affecting agricultural production and causing a decline in agricultural production efficiency. In order to study the development level of green finance in Beijing-Tianjin-Hebei region and its role in agricultural development, this paper establishes a green financial index system and uses the entropy method to measure and analyze the development level of green finance in Beijing-Tianjin-Hebei region. Based on DEA-Malmquist model, the agricultural carbon emission efficiency in Beijing-Tianjin-Hebei region was analyzed. The coupling coordination degree analysis of the two is carried out to analyze the regional differences of Beijing, Tianjin and Hebei. In the study found that the Beijing-Tianjin-Hebei region green financial development is still in its infancy, there is still room for greater development; the efficiency of agricultural carbon emission in Beijing-Tianjin-Hebei region is benign, and the technical efficiency of agricultural carbon emission in Beijing and Tianjin needs to be improved. The coupling level of green financial development level and agricultural carbon emission efficiency is low, and the coordination between the two needs to be continuously improved. This paper gives the following suggestions for the above problems : accelerate the construction of green financial market system; to promote the six high energy-consuming industries to green low-carbon development; attaching importance to the combination of financial talents and green financial development; Beijing plays a leading role in providing talents and technical support for Tianjin and Hebei Province, driving Tianjin.
