How to read these labor-market indices
This page shows three series: the Hiring Momentum Index, where 50 is neutral; the Pay Transparency Index, the share of measurable open roles whose employer states pay, overall and for EU-located roles; and the Stated Pay Index, a Laspeyres fixed-basket index of employer-stated pay.
Where a latest point exists, the page prints that value, adding a percent sign plus an EU percent and a sample size on the Pay Transparency Index; where it does not, the page prints an em dash and says the series publishes only once its gates are met, with gaps never interpolated.
The banner states the series are written forward daily and never backfilled, and the page gives a citation, a methodology link, and CSV and JSON downloads of these same indices.
被指數化的勞動市場
三條可引用的序列，全部建立在標準統計設計上——PMI 式的徵才擴散指數、歐盟指令意在改變的薪酬透明占比，以及控制組成的明示薪酬指數。每個點都經過測量、附版本、可重現；樣本過薄的日子發布為空缺，絕不推估。
HMI · Hiring Momentum Index
追蹤面板上 PMI 式的週度擴散指數：開缺擴張的雇主占比對上收縮的占比，50 為榮枯線。逐公司計相對變動，面板本身的成長推不動指數。
方法論
| design | PMI-style weekly diffusion |
| reporter_gate | >= 5 live openings at both endpoints of a 7-day window |
| publish_gate | >= 50 reporters per point |
| formula | (% expanding + 0.5 x % unchanged) x 100 |

PTI · Pay Transparency Index
可測開放職缺中雇主明示薪酬的占比——整體與歐盟職缺雙序列。這正是歐盟薪酬透明指令意在改變的數列，我們按日實測，而非按年調查。
方法論
| design | direct daily measurement over the deduplicated panel |
| denominator | open roles on platforms whose full text is observable (salary-blind platforms excluded) |
| eu_series | same measure restricted to EU-located roles |

SPI · Stated Pay Index
以職能 × 國家細格為基礎的 Laspeyres 固定籃指數，權重凍結於基期——組成漂移無法偽裝成薪資變動。
方法論
| design | Laspeyres fixed basket over job_family x country cells |
| base_period | first 5 qualifying days, cell medians and weights averaged (a cell needs >= 3 base-window days) |
| cell_gate | >= 30 stated ranges per cell-day |
| publish_gate | >= 10 common cells per point |
| weights | frozen at base-period average stated-range counts; renormalized over the cells present on each day (coverage_pct reports the retained weight share) |
| note | composition-controlled: panel growth cannot masquerade as pay movement |
