中国自主车企2018-2024年发明专利数据集

1. 预处理阶段：首先，需要对从第三方专利检索网站收集来的五家自主车企2018-2024年的专利申请、授权数据进行预处理，这一阶段的目标是确保数据适合后续的加工操作；2. 数据加工阶段：根据五家车企近五年的专利授权量和结案量，计算出五家车企的专利授权率和结案率。这包括选择确定计算规则（如统计参数、进统计维度）以及安排数据的对比分析；3. 定时监控与调整：在实际数据处理过程中，根据不同平台披露的数据统计完善，并根据需要进行调整，以确保最佳的处理效果。1. Preprocessing Stage: First, preprocess the patent application and grant data of five independent domestic automakers spanning from 2018 to 2024, collected from third-party patent retrieval websites. The objective of this stage is to render the data suitable for downstream processing workflows. 2. Data Processing Stage: Calculate the patent grant rate and case closure rate for the five automakers based on their patent grant volumes and case closure volumes during the 2018-2024 period. This entails selecting and defining calculation rules including statistical parameters and statistical dimensions, as well as arranging comparative analyses of the dataset. 3. Scheduled Monitoring and Adjustment: During the actual data processing workflow, refine the data statistics disclosed by different platforms and make corresponding adjustments as needed to ensure optimal processing outcomes.
