PLS-SEM 統計分析完整流程
步驟 1:評估測量模型(Measurement Model)
- 指標信度:外部負荷量(outer loadings)≥ 0.708;0.40–0.708 之間視刪除後對 CR/AVE 的影響決定去留。
- 內部一致性信度:Cronbach's α 與組合信度 CR 均應 ≥ 0.70(CR > 0.95 反而代表題項重複)。
- 收斂效度:AVE ≥ 0.50。
- 區別效度:優先看 HTMT < 0.85(寬鬆 0.90),輔以 Fornell-Larcker 準則(√AVE 大於構念間相關)。
💡 測量模型未通過前,不要解讀結構模型——量尺不準,路徑係數沒有意義。
步驟 2:評估結構模型(Structural Model)
- 共線性:內部 VIF < 3(上限 5)。
- 路徑係數顯著性:執行 Bootstrapping(建議 5,000 或 10,000 次重抽),|t| > 1.96 或 p < 0.05 即顯著。
- 解釋力 R²:0.75 高 / 0.50 中 / 0.25 弱(依研究領域調整期待)。
- 效果量 f²:0.02 小 / 0.15 中 / 0.35 大。
- 預測相關性 Q²(Blindfolding 或 PLSpredict):Q² > 0 表示模型對該內生構念具預測相關性。
💡 報告路徑係數時,務必同時呈現 β、t 值、p 值與信賴區間。
步驟 3:撰寫結果與結論
- 依序報告:樣本描述 → 測量模型(信度、收斂效度、區別效度各一張表)→ 結構模型(路徑圖 + 假設檢定表)。
- 每條假設寫成「H1:X 對 Y 有正向影響(β = .xx, t = x.xx, p < .05,獲得支持)」的格式。
- 不顯著的假設要誠實報告,並在討論章節提出可能解釋。
- 結論需回應研究目的:理論貢獻與實務意涵。
- 限制與未來研究:橫斷面資料、共同方法變異(CMV)、樣本代表性等。

常見問題
- AVE 不到 0.5 怎麼辦?
- 找出外部負荷量最低的題項(通常 < 0.6),一次刪一題並重新估計,直到 AVE ≥ 0.5。刪題過程要寫進論文。
- HTMT 超過 0.9 怎麼辦?
- 兩個構念在統計上難以區分。檢查題項語意是否重疊,考慮合併構念,或用 bootstrapping 檢定 HTMT 信賴區間是否包含 1。
- 路徑不顯著,論文還能寫嗎?
- 可以,而且必須誠實報告。不顯著的結果在討論章節提出解釋,往往是論文的亮點。
- Bootstrapping 要設幾次?
- 最終分析建議 5,000 或 10,000 次重抽,並回報 95% 信賴區間(建議用 percentile bootstrap)。
- 樣本數要多少才夠?
- 最低經驗法則為「10 倍法」,但更建議用 G*Power 以統計檢定力 0.8、效果量 f² = 0.15 估算所需樣本。
Step 1: Assess the Measurement Model
- Indicator reliability: outer loadings ≥ 0.708; for 0.40–0.708, decide based on the impact of removal on CR/AVE.
- Internal consistency: Cronbach's α and composite reliability CR should both be ≥ 0.70 (CR > 0.95 signals redundant items).
- Convergent validity: AVE ≥ 0.50.
- Discriminant validity: rely primarily on HTMT < 0.85 (lenient 0.90), supplemented by the Fornell-Larcker criterion (√AVE exceeds inter-construct correlations).
💡 Do not interpret the structural model before the measurement model passes — with an unreliable instrument, path coefficients are meaningless.
Step 2: Assess the Structural Model
- Collinearity: inner VIF < 3 (upper bound 5).
- Path significance: run Bootstrapping (5,000 or 10,000 subsamples recommended); |t| > 1.96 or p < 0.05 is significant.
- Explanatory power R²: 0.75 substantial / 0.50 moderate / 0.25 weak (adjust expectations by field).
- Effect size f²: 0.02 small / 0.15 medium / 0.35 large.
- Predictive relevance Q² (Blindfolding or PLSpredict): Q² > 0 indicates predictive relevance for that endogenous construct.
💡 When reporting path coefficients, always present β, t value, p value and confidence intervals together.
Step 3: Write Up Results & Conclusions
- Report in order: sample description → measurement model (one table each for reliability, convergent and discriminant validity) → structural model (path diagram + hypothesis table).
- Write each hypothesis as "H1: X positively influences Y (β = .xx, t = x.xx, p < .05, supported)".
- Report non-significant hypotheses honestly and offer explanations in the discussion.
- Conclusions should answer the research objectives: theoretical contributions and practical implications.
- Limitations & future research: cross-sectional data, common method variance (CMV), sample representativeness.

FAQ
- What if AVE is below 0.5?
- Find the items with the lowest outer loadings (usually < 0.6), remove one at a time and re-estimate until AVE ≥ 0.5. Document the process in your paper.
- What if HTMT exceeds 0.9?
- The two constructs are statistically indistinguishable. Check for overlapping item wording, consider merging constructs, or bootstrap the HTMT confidence interval to test whether it contains 1.
- A path is not significant — can I still publish?
- Yes, and you must report it honestly. Explaining non-significant results in the discussion is often a highlight of the paper.
- How many bootstrap subsamples?
- For final analysis use 5,000 or 10,000 subsamples and report 95% confidence intervals (percentile bootstrap recommended).
- How large should my sample be?
- The "10-times rule" is the bare minimum; better to use G*Power with power 0.8 and effect size f² = 0.15 to estimate the required sample.
