Kazakhstan public-procurement supplier panel, 2021–2026

A de-identified, harmonised supplier-level panel of every bid, contract, and lot processed by Kazakhstan's national e-procurement portal (goszakup.gov.kz) between 1 January 2021 and 30 April 2026.

The archive contains four primary tables — a bid panel (40,627,979 rows, one row per supplier–lot application), a contract panel (9,400,830 rows, one row per signed contract), a lot panel (10,209,315 rows, one row per advertised lot), and a supplier index (151,374 suppliers with at least five bids in the window) — together with 16 decoded reference (lookup) tables that translate every coded field from the source platform into English labels. Direct identifiers (supplier tax id, customer organisation id, contract number, agreement id) are SHA-256 hashed with a project salt and truncated to 16 hex characters; the hash is stable across panels so joins are preserved, but actors cannot be re-identified from the released data alone.

The dataset spans the January 2025 procurement reform (revised dumping threshold, expanded use of the rating-based mechanism) and covers three procurement methods used on the platform: open competition (method 2), price-quotation auctions (method 3), and the rating system introduced in 2022 (method 188). The accompanying README.md contains the full variable dictionary, joining conventions, and known caveats.

Companion article: a Data in Brief paper describing the data set is in preparation. The processing pipeline that produced the files is released separately on Zenodo and on GitHub.

本数据集为经去标识化处理的统一标准化供应商级面板数据，涵盖2021年1月1日至2026年4月30日期间哈萨克斯坦国家电子采购门户（goszakup.gov.kz）所处理的全部投标、合同及标段（lot）信息。

该数据集归档包含四张核心数据表：投标面板（bid panel，共40,627,979行，每条记录对应一份供应商-标段投标申请）、合同面板（contract panel，共9,400,830行，每条记录对应一份已签署合同）、标段面板（lot panel，共10,209,315行，每条记录对应一则发布的标段招标信息），以及供应商索引表（supplier index，包含本统计周期内至少提交过5次投标的151,374家供应商）；此外还附带16张解码参考（查找）表，可将源平台的所有编码字段转换为英文标签。

直接标识符（包括供应商税号、采购方组织ID、合同编号、协议ID）均已通过项目盐值进行SHA-256哈希处理，并截断为16位十六进制字符；该哈希值在各面板间保持稳定，可保留数据关联关系，但仅通过本次发布的数据无法反向识别出具体市场主体。

本数据集覆盖2025年1月实施的采购改革（修订了倾销阈值，扩大了基于评分的采购机制的应用范围），涵盖该平台上使用的三种采购方式：公开竞争（方式2）、报价拍卖（方式3），以及2022年推出的评分系统（方式188）。随附的README.md文件包含完整的变量词典、关联规则及已知局限性说明。

配套文章：一篇介绍该数据集的《数据简报》（Data in Brief）论文正在筹备中。生成该数据集文件的处理管线已分别在Zenodo及GitHub平台公开发布。
