1. Introduction
- Purpose: briefly introduce the study.
-
What to include:
- Who are the authors and year.
- What they studied (topic, context, scope).
- Why the study is important or relevant.
Example: “Breivik et al. (2023) studied inventory turnover efficiency by considering both firm-level and environmental factors, highlighting that performance is shaped not only by financial ratios but also by external conditions.”
2. Key Research Methodologies
- Purpose: explain how the research was conducted.
-
What to include:
- The method used (e.g., Stochastic Frontier Analysis, panel regression).
- The dependent variable (always say what the DV is — here, inventory turnover).
- The independent variables (firm size, sales growth, gross margin, capital intensity, environmental factors).
- The model form (equation or regression design).
Example: “Breivik et al. (2023) applied Stochastic Frontier Analysis (SFA) with inventory turnover ratio as the dependent variable (COGS ÷ Average Inventory). Explanatory variables included firm size, sales growth, gross margin, and location. The model took the form ITit=f(Xit;β)exp(vit−uit)IT_{it} = f(X_{it};\beta)\exp(v_{it}-u_{it})ITit=f(Xit;β)exp(vit−uit), where uitu_{it}uit captures inefficiency.”
3. Key Findings and Research Gaps
- Purpose: summarize what the study found, and point out its limits.
-
What to include:
- The results (positive/negative correlations, main drivers).
- Why the results matter.
- Limitations (only one industry, only U.S./Norway, not digital platforms).
- Future research directions (apply to platform supply chains).
Example: “The study found that sales growth is positively associated with turnover efficiency, while firm size has a mixed effect. Environmental context (urban vs. rural) also mattered significantly. However, the research is limited to Norwegian retail chains and does not address platform-based retail. Future studies could extend the framework to digital resale platforms such as GOAT or StockX.”
