Export-Structure Similarity and Higher-Unit-Value Positioning in Korea’s Automotive-Parts Trade

This dataset provides the processed data and workbook-based replication materials for the study “Export-Structure Similarity and Higher-Unit-Value Positioning in Korea’s Automotive-Parts Trade.” The study examines Korea’s bilateral automotive-parts trade with China, the United States, and Japan during 2000–2019, treated as a historical pre-pandemic benchmark. It uses a fixed classification of 213 HS6 products and six partner–product-group panels covering electrical and electronics parts and general parts. The 21-worksheet repository workbook documents the HS6 product classification, product-group IPC coverage lists, annual trade indicators, available patent counts, two-year-lagged patenting gaps, and core variable definitions. The IPC lists contain 195 electrical and electronics classes and 285 non-overlapping general-parts classes, totalling 480 classes after 16 cross-list duplicates were removed. These are product-group coverage lists, not pairwise HS6–IPC links. Additional worksheets document formula-based annual ESI×TSI states, full-sample and sub-period transition counts and proportions, RCA×IIT classifications, annual structural position index (SPI) series, SPI leave-one-component-out checks, state summaries, sensitivity checks, and reproducibility audits. The workbook supports verification and reproduction of the reported results from the processed data. The repository does not include the original UN Comtrade or USPTO data, raw-data extraction scripts, external analysis scripts, or exact figure-generation code. Alternative unit-value bands cannot be recomputed because the deposited annual aggregates do not contain HS6-level quantity, net-weight, or unit-value inputs. The underlying raw data are available from UN Comtrade and the USPTO, subject to their access conditions. The analyses are descriptive and do not identify causal effects.本数据集为研究《韩国汽车零部件贸易中的出口结构相似度与更高单位值定位》提供了经过预处理的数据与基于工作簿的复现材料。本研究以2000年至2019年作为疫情前的历史基准期，考察了韩国与中国、美国、日本的双边汽车零部件贸易。研究采用213项协调制度6位编码（HS6）产品的固定分类标准，以及覆盖电气电子零部件与通用零部件的6组伙伴国-产品组面板数据集。该含21个工作表的工作簿记录了HS6编码产品分类、产品组国际专利分类（IPC）覆盖清单、年度贸易指标、可用专利存量、两年滞后专利缺口以及核心变量定义。其中IPC覆盖清单包含195项电气电子类别与285项非重叠通用零部件类别，在剔除16项跨类别重复项后总计480个类别。需注意，此处仅为产品组覆盖清单，而非HS6编码与IPC的配对链接。其余工作表则记录了基于公式计算的年度出口结构相似度指数（ESI）×贸易专业化指数（TSI）状态、全样本与子时段的转型计数及占比、显性比较优势（RCA）×产业内贸易（IIT）分类、年度结构性定位指数（SPI）序列、SPI留一成分检验、状态汇总、敏感性检验与可复现性审计。该工作簿可用于验证并复现基于预处理数据得到的所有研究结果。本数据集未包含联合国商品贸易统计数据库（UN Comtrade）或美国专利商标局（USPTO）的原始数据、原始数据提取脚本、外部分析脚本或精确的图表生成代码。由于存档的年度汇总数据未包含HS6层级的数量、净重或单位值输入项，无法重新计算备选单位值区间。原始底层数据可根据对应平台的访问要求从UN Comtrade与USPTO获取。本研究仅开展描述性分析，未识别因果效应。
