Replication Code for The Impact of the Digital Economy on Industrial GTFP in the YEB: A Nexus of Agglomeration, Innovation, and Spatial Spillovers

Manuscript Title: The Impact of the Digital Economy on Industrial GTFP in the YEB: A Nexus of Agglomeration, Innovation, and Spatial SpilloversDescription: This folder contains the complete datasets, code, and weight matrices required to replicate the empirical results of the study. The files are organized into three logical components:GTFP Calculation (MATLAB):mainfx0.m, SBM_DDF.m, SBM_DDF_GML.m: MATLAB scripts to calculate the SBM-DDF model and GML index.GTFP_calculate2.xlsx: Raw input data for the efficiency calculation.Digital Economy Index (Stata):DigitalEconomyCalculation.do: Stata code for entropy weight calculation.DataDigitalEconomyCalculation.xlsx: Raw indicator data.Main Econometric Analysis (Stata):Stata code.do: Master script that reproduces all descriptive statistics, baseline regressions, threshold effects, mechanism analysis, and spatial econometric models (SDM/SAR/SEM).Data for Stata.xlsx: The final cleaned dataset used for regression.Wmat.dta & Economic Geographical Weight Matrix...xlsx: Spatial weight matrices.
