The method is simple yet powerful in estimating cost behaviors and predicting future trends. Additionally, linear regression allows for analyzing trends over time and isolating the effects of specific factors, such as the impact of automation on reducing labor costs or the role of Gigafactories in lowering transportation expenses. By identifying these patterns, Tesla can make informed decisions to optimize costs and maintain its competitive edge in the EV industry. This approach provides actionable insights for forecasting future financial performance and improving operational efficiency.

2.2. Linear Regression

The data used for this analysis was extracted from Tesla’s financial statements from 2022 to 2023. Key cost components were selected as independent variables based on their relevance to Tesla's overall cost structure. The dependent variable in this analysis is the "Total Cost of Revenues" (Y), which includes direct production costs, labor, and materials. The following variables in Table 1were selected as independent variables (X₁, X₂, … X₁₀):

Table1: Independent variable definition.

Each of these variables was selected due to their direct or indirect impact on Tesla’s cost structure, either through production efficiency, financial obligations, or operational scaling.

Financial reports for each quarter from 2022 to 2023 were sourced from Tesla's official website. Ten key variables were selected from these reports to serve as the independent variables for the linear regression analysis. Quarterly data were chosen because they provide a detailed and time-sensitive perspective on Tesla's financial performance, capturing short-term fluctuations that may not be observable in annual or biannual reports. This approach enhances the precision of the regression model by reflecting more granular trends and patterns."

A multivariate linear regression model was applied to the dataset, using Tesla's Total Cost of Revenues as the dependent variable and the ten aforementioned independent variables as predictors. The corresponding results are shown in Figure 1.

The general form of the linear regression equation used is:

\( Y={β_{0}}+{β_{1}}{X_{1}}+{β_{2}}{X_{2}}+⋯+{β_{10}}{X_{10}}+ϵ \) (1)

The regression model was first tested for multicollinearity using the Variance Inflation Factor. Variables with a VIF greater than 5 indicate potential multicollinearity, suggesting that these variables are highly correlated with each other. Multicollinearity can distort the regression results by inflating the variance of the coefficient estimates, making it difficult to assess the individual effect of each variable.

Table2: Verify the VIF of R value.

By calculating this, it can tell that Total Assets, Total Liabilities, Inventory, and Total Revenues exhibited VIF values higher than 10, indicating substantial multicollinearity. This suggests that these variables are strongly correlated with each other, as is expected in a company like Tesla, where assets, liabilities, and revenues grow in tandem with production scale and market reach.

Consequently, only the variables with a Variance Inflation Factor greater than 5 were selected for inclusion in the final analysis, as these variables demonstrated a higher degree of multicollinearity. By focusing on these variables, the analysis aimed to account for potential multicollinearity while ensuring that only the most impactful predictors were used. After selecting the appropriate variables, the linear regression model was constructed, and the resulting plot was generated based on both the R-squared value and the VIF values. This approach allowed for a more robust analysis of the relationships between the independent and dependent variables, ultimately improving the model’s accuracy and interpretability.
