Digital Intelligence and Agricultural Non-Point Source Pollution in China, 2014-2023

This dataset contains provincial-level panel data for 31 Chinese provinces covering the period 2014–2023. It comprises three main components: (1) Digital intelligence integration index constructed from digital infrastructure, technology application, intelligent equipment, and digital entity capabilities; (2) Agricultural non-point source pollution indicators including chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP); (3) Control variables including agricultural structure, economic development, fiscal agricultural expenditure, and topographic features. Data sources include the National Bureau of Statistics of China, China Agricultural Yearbook, and provincial statistical yearbooks.本数据集涵盖2014-2023年中国31个省份的省级面板数据，共包含三大核心组成部分：(1) 数字智能融合指数：该指数由数字基础设施、技术应用、智能装备及数字实体能力四大维度构建而成；(2) 农业面源污染指标：涵盖化学需氧量（Chemical Oxygen Demand, COD）、总氮（Total Nitrogen, TN）与总磷（Total Phosphorus, TP）；(3) 控制变量：包含农业结构、经济发展水平、财政支农支出及地形特征。本数据集的数据来源包括中国国家统计局、《中国农业年鉴》及各省级统计年鉴。
