在2019-2022年間，全球化的新冠肺炎疫情，重大衝擊影響了各國經濟發展。當前經濟衰退的不確定性，也抑制了作為全球經濟增長指標的企業活動和盈利能力。尤其是過去所出現的高就業增長和低生產力增長的現像，而今愈演愈烈。在當前全球經濟環境低迷緊縮的挑戰中，企業如何有效利用人力資源、降低管理費用和提高生產效率變得非常重要。本研究旨在討論影響企業的勞動生產力的三個關鍵投資因素。本文採用理論文獻探討及理性邏輯推導，建立了人力資源規劃、高績效工作實踐和人力資源冗餘的投資對企業勞動生產力的研究模型，並提出三項研究命題內容分別為，研究命題一:企業在人力資源規劃的投資，會正向影響企業勞動生產力。研究命題二: 企業在高績效工作實踐的投資，會正向影響企業勞動生產力。研究命題三: 企業在人力資源冗餘的投資，會正向影響企業勞動生產力。本文的研究結果，指出企業可通過加強人力資源規劃、高績效工作實踐和人力資源冗餘的投資，來提升企業的企業勞動生產力。

From 2019 to 2022, the globalized COVID-19 epidemic has had a major impact on the economic development of various countries. Uncertainty surrounding the current recession is also dampening corporate activity and profitability, indicators of global economic growth. In particular, the phenomenon of high employment growth and low productivity growth in the past has intensified. In the current global economic downturn and austerity challenges, it is very important for enterprises to effectively utilize human resources, reduce management costs, and improve production efficiency. This study aims to discuss three key investment factors that affect a firm's labor productivity. This study uses theoretical literature discussion and rational logic derivation to establish a research model of human resource planning, high-performance work practices, and human resource slack investments on firm’s labor productivity and proposes three research propositions. Research proposition 1: Investments in human resource planning will positively affect the labor productivity. Research Proposition 2: Investments in high-performance work practices will positively affect the labor productivity. Research Proposition 3: Investments in human resource slack will positively affect the labor productivity. The findings of this study point out that firms can improve labor productivity by strengthening investments in human resource planning, high-performance work practices, and human resource slack.
