Beijing Tianyu Communication Co. Ltd.: Winning in the 3G Era (B)
Bibliographic record
Abstract
2G时代，手机作为一种独立的消费电子产品存在，品牌厂商在手机市场握有话语权，然而自从进入3G时代，电信运营商处于产业链的主导性地位，手机市场面临巨大调整。创立于2002年的北京天宇朗通通信设备有限责任公司，曾是中国市场最大的三星手机分销商，后来进军手机制造行业。虽然早期经历了很多挫折，但是在六年之后，天宇超越其他国产手机制造商，成为国产品牌销量冠军。2008年，天宇在中国市场销售出2400万部手机，市场份额超过6%，仅次于诺基亚、三星和摩托罗拉。然而，面对3G时代市场的激烈竞争，天宇无法继续依赖其在2G手机市场的独特优势来源。雪上加霜的是，由于经济衰退，2G手机的市场需求急剧下滑。天宇朗通掌门人荣秀丽很快在公司发起一项针对3G手机市场的运动，几乎重新配置新3G业务的所有资源，然而新的战略却遭遇来自公司内外的巨大挑战。本系列共两个案例，案例（B）描述了在这样一个不断变化的市场环境中，天宇如何解决进入新3G市场的问题，以及如何摆正在新的产业链环境中的位置，如何借力海外市场续写2G时代的成功。

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
