Open-source R toolkit: Transferable green digital strategies for African manufacturing & mining SMEs, evidence from Chinese listed industrial firms # Green Digital Africa Toolkit **Author:** kaluba-jacob **Date:** July 2026 ## 1. Project Overview This repository contains the complete reproducible econometric analysis code for the **"Green Digital Africa"** empirical research project. The study investigates the impact of **Digital Business Model Innovation** on **Green Total Factor Productivity (GTFP)** using a panel dataset of Chinese listed firms from 2016 to 2024. The full analysis pipeline includes three standard phases of empirical research: - **Phase 1**: Data cleaning, variable construction, baseline regression, and robustness checks - **Phase 2**: Heterogeneity analysis (boundary conditions of the effect) - **Phase 3**: Mechanism analysis (mediation channels) ## 2. Project Structure ``` The project follows a modular, beginner-friendly RStudio structure with clear separation of raw data, analysis scripts, and output tables.
