3.1 Interpretation and Discussion of Statistical Analysis
The results of this study provide a comprehensive empirical synthesis of the relationships among corporate social responsibility (CSR), sustainable supply chain management practices (SSCMP), organizational resilience, innovation, and performance within the broader well-being economy framework. Drawing on the systematic review and meta-analytic procedures outlined earlier, the findings integrate descriptive study characteristics, pooled effect sizes, and graphical diagnostics to assess robustness, precision, and potential bias.
Table 1 summarizes the core characteristics of the studies included in the systematic review and meta-analysis. The table demonstrates that the evidence base is methodologically diverse yet conceptually aligned, encompassing multiple industries, geographic regions, and firm sizes. Most studies employ cross-sectional survey designs with regression-based analytical techniques, while a smaller subset uses longitudinal data. Sample sizes vary considerably, indicating that study precision differs across the dataset, a factor explicitly addressed in the weighting procedures of the meta-analysis. Collectively, the studies represented in Table 1 confirm that CSR and sustainability-related constructs have been operationalized with reasonable consistency, allowing for meaningful aggregation of effect sizes.
The pooled statistical outcomes reported in Table 2 provide the central quantitative evidence of the study. The table presents combined effect sizes, standard errors, and significance levels derived from the random-effects meta-analysis. Across models, the results indicate statistically significant and substantively meaningful relationships between CSR-related variables and organizational outcomes. Internal CSR demonstrates a positive and significant association with SSCMP, suggesting that employee-focused and internally embedded responsibility initiatives play a critical role in operationalizing sustainability within supply chains. External CSR also exhibits a strong positive effect, reinforcing the importance of stakeholder engagement, ethical sourcing, and social legitimacy in shaping sustainable supply chain behaviors. The magnitude of these coefficients, as reported in Table 2, indicates moderate to strong effects, supporting the argument that CSR is not merely symbolic but functionally embedded in organizational processes.
Beyond direct relationships, the results also reveal that SSCMP serves as a crucial mechanism linking CSR to broader organizational outcomes. The pooled estimates in Table 2 show that firms with stronger sustainable supply chain practices report higher levels of organizational resilience, innovation capability, and overall performance. These findings align with the well-being economy perspective, which emphasizes systemic resilience and long-term value creation over short-term financial optimization. The statistical significance of these relationships suggests that sustainability-oriented supply chain investments yield tangible organizational benefits, particularly in environments characterized by uncertainty and disruption.
The variability in effect sizes observed across studies, as reflected in heterogeneity statistics reported in Table 2, further enriches the interpretation of results. While heterogeneity is present, it remains within acceptable ranges for organizational and management research, justifying the use of a random-effects model. This heterogeneity reflects contextual differences such as regional institutional environments, industry characteristics, and measurement approaches rather than fundamental inconsistencies in the underlying relationships. Importantly, the direction of effects remains consistently positive across studies, reinforcing the robustness of the conclusions.

Graphical analysis provides additional insight into the meta-analytic findings. Figure 2, which is correctly identified as a forest plot, visually presents individual study effect sizes alongside the pooled estimates. Each horizontal line represents a study’s confidence interval, while the central marker indicates the estimated effect size. The forest plot reveals that the majority of studies cluster around the overall mean effect, with confidence intervals largely overlapping the pooled estimate. This visual convergence supports the statistical evidence in Table 2, indicating that no single study disproportionately drives the results. Moreover, the forest plot illustrates that even studies with smaller sample sizes generally align in direction with larger, more precise studies, further strengthening confidence in the aggregated findings.
In contrast, Figure 3 is identified as a funnel plot, used to assess potential publication bias and small-study effects. The funnel plot displays study effect sizes plotted against a measure of precision, typically the standard error. Visual inspection of Figure 3 suggests a largely symmetrical distribution around the pooled effect size, particularly among studies with higher precision. While minor asymmetry may be observed among smaller studies, this pattern is common in social science meta-analyses and does not necessarily indicate systematic publication bias. The overall symmetry of the funnel plot supports the conclusion that the meta-analytic results are not unduly influenced by selective reporting or the overrepresentation of statistically significant findings.
Taken together, the combined interpretation provides a coherent and methodologically sound account of the empirical evidence. The results demonstrate that CSR—both internal and external—has a statistically significant and practically meaningful impact on sustainable supply chain management practices. In turn, SSCMP contributes positively to organizational resilience, innovation, and performance. These findings empirically substantiate theoretical claims that well-being-oriented economic models can be operationalized at the firm level through sustainability-focused strategies.
Importantly, the statistical evidence also highlights the precision and reliability of the estimated effects. As shown in Table 2, standard errors are relatively small for most pooled estimates, indicating high confidence in the reported relationships. The consistency observed in the forest plot (Figure 2) and the absence of severe asymmetry in the funnel plot (Figure 3) further reinforce the credibility of the results. Together, these diagnostic tools confirm that the meta-analytic conclusions are both statistically robust and substantively meaningful.
The results section provides strong empirical support for the central premise of this study: that integrating CSR into sustainable supply chain practices is a viable and effective pathway for enhancing organizational resilience, innovation, and performance within a well-being economy framework. The convergence of tabular and graphical evidence underscores the reliability of these findings and establishes a solid empirical foundation for subsequent discussion and policy implications.
3.2 Interpretation and Discussion of Forest and Funnel Plots
The graphical analyses presented in this study, specifically the forest plot (Figure 2) and the funnel plot (Figure 3), provide critical insight into the consistency, precision, and potential biases in the meta-analytic dataset. Both plots serve complementary functions in synthesizing the findings from the selected studies, allowing for a robust assessment of effect sizes and the reliability of the pooled estimates.
The forest plot (Figure 2) is a standard tool in meta-analysis for visually representing individual study effect sizes and their corresponding confidence intervals. In this figure, each horizontal line represents the 95% confidence interval of a particular study’s estimated effect, while the central marker denotes the effect size (B) for that study. The pooled effect size, derived using a random-effects model to account for between-study variability, is displayed at the bottom of the plot with a diamond-shaped marker, reflecting the overall estimate across all included studies. The forest plot allows us to immediately discern both the magnitude and direction of individual study effects in relation to the overall effect.
From Figure 2, it is evident that most studies, including Cardoso et al. (2025) and Du et al. (2023), report positive and statistically significant relationships between predictor variables such as organizational resilience, innovation, investment strategy, telework strategy, and macroeconomic indicators like country GDP, with respective outcome variables. The confidence intervals for these studies mostly overlap with the pooled estimate, indicating a high degree of consistency in the direction of effects. For instance, Cardoso et al.’s (2025) work on organizational resilience and innovation shows moderately large effect sizes with narrow confidence intervals, suggesting that these predictors consistently enhance organizational performance across different contexts. Conversely, Du et al.’s (2023) studies on maritime distance and trade volume show a negative relationship, yet their confidence intervals remain precise, reflecting reliable estimation despite the inverse association. This visual evidence confirms the robustness of the meta-analytic findings and indicates that no single study unduly drives the overall effect.
The forest plot also highlights variability in the precision of individual study estimates. Studies with larger sample sizes, such as Cardoso et al. (2025) with N=320, display narrower confidence intervals, reflecting higher precision, whereas studies with smaller or more variable datasets exhibit wider intervals. This variability is addressed in the meta-analytic framework through weighted aggregation, ensuring that more precise estimates contribute proportionally to the pooled effect size. The overall visualization underscores the reliability of the findings and demonstrates that both organizational and macroeconomic predictors exhibit meaningful and statistically significant impacts on their respective outcomes.
Complementing the forest plot, the funnel plot (Figure 3) provides a diagnostic assessment of potential publication bias and small-study effects. In a funnel plot, individual study effect sizes are plotted on the x-axis against a measure of precision, typically the inverse of the standard error, on the y-axis. The underlying expectation is that in the absence of bias, the plot should resemble an inverted symmetrical funnel: studies with higher precision cluster near the pooled effect size, while smaller, less precise studies scatter more widely at the bottom. Symmetry in the funnel plot suggests that the aggregated meta-analytic results are not significantly influenced by selective reporting or the overrepresentation of statistically significant results.
Figure 3 shows a predominantly symmetrical distribution of studies around the pooled effect size, indicating minimal risk of publication bias. High-precision studies, typically those with larger sample sizes, cluster near the top of the funnel close to the overall effect estimate, whereas studies with smaller sample sizes are more dispersed toward the bottom. Although minor asymmetry appears among a few smaller studies, this is common in social science meta-analyses and may reflect contextual or methodological differences rather than systematic bias. For example, Du et al.’s (2023) analysis of Shanghai GDP exhibits a slightly wider spread, possibly due to regional economic variability or measurement differences, yet it does not significantly distort the overall pooled estimate. The funnel plot thereby reassures that the meta-analytic results presented in Table 2 are reliable and robust across diverse studies and contexts.
The combination of forest and funnel plots allows for a nuanced interpretation of both the magnitude and reliability of observed effects. The forest plot demonstrates that effect sizes for organizational performance predictors—particularly organizational resilience and innovation—are consistently positive, while macroeconomic predictors such as sample country GDP also display strong positive effects on trade volume. Conversely, negative effects, such as maritime distance on trade volume, are precisely estimated and conceptually coherent, reflecting the expected economic relationship of distance as a barrier to trade. The forest plot’s clarity in depicting these patterns is essential for interpreting the substantive significance of the findings, as it highlights both the direction and the precision of effects across studies.
Simultaneously, the funnel plot confirms that these findings are unlikely to be artifacts of selective reporting. Symmetry suggests that smaller studies are not systematically overrepresented based on statistical significance, enhancing confidence in the generalizability of the pooled results. In addition, the funnel plot helps identify areas where heterogeneity might arise. Slight dispersion at the base of the funnel indicates natural variation due to differences in study design, industry sector, sample characteristics, or regional economic conditions. Such heterogeneity is expected in applied social science research and is appropriately managed through random-effects modeling, as reflected in the statistical analyses.
Taken together, the interpretation of the forest and funnel plots provides strong empirical support for the study’s central propositions. The forest plot visually reinforces the positive and meaningful contributions of organizational resilience, innovation, investment strategy, and macroeconomic factors to respective outcomes, while the funnel plot mitigates concerns about bias and validates the robustness of these findings. Both plots illustrate that the observed effect sizes are consistent, precise, and reliable,

This forest plot displays the standardized regression coefficients (effect sizes) and their 95% confidence intervals for each predictor–outcome relationship examined across the studies included in the meta-analysis. Each horizontal line represents one study estimate, with the marker size reflecting relative study weight, and the diamond at the bottom indicating the pooled overall effect. The plot allows visual comparison of effect direction, magnitude, and consistency across studies.

Figure 3. Funnel Plot Assessing Publication Bias in the Meta-Analysis. This funnel plot plots each study's effect size against its standard error (a measure of precision) to visually assess the likelihood of publication bias and small-study effects. A roughly symmetrical, funnel-shaped scatter around the pooled effect indicates low risk of bias, whereas asymmetry would suggest missing studies or selective reporting. The pattern shown here supports the reliability of the pooled meta-analytic estimates reported in Table 2.
offering credible evidence for integrating CSR, SSCMP, and well-being-oriented strategies in organizational and policy decision-making.
The forest and funnel plots collectively affirm the meta-analytic evidence’s integrity and interpretive value. The forest plot demonstrates clear, directionally consistent, and statistically significant relationships across studies, while the funnel plot verifies that these effects are not substantially influenced by publication bias. Together, these visualizations enhance understanding of the empirical patterns underlying sustainable supply chain practices, organizational resilience, and macroeconomic determinants, providing a comprehensive foundation for the study’s theoretical and practical implications in advancing a well-being economy. The graphical analyses thus underscore both the statistical robustness and the real-world relevance of the observed effects, reinforcing the importance of evidence-based strategies in post-pandemic organizational and economic transformations.
