Core Insights - The article discusses the measurement of green total factor productivity (GTFP) for listed companies from 2000 to 2024, incorporating environmental pollution into the evaluation system [1][2]. Measurement Methodology - The GTFP is measured using a non-radial SBM index, with inputs including labor (number of employees), capital (net fixed assets), and energy (standard coal consumption) [1][4]. - The expected output is represented by the company's operating income, while the non-expected output is calculated based on the employment ratio of the company's workforce to the urban employment in the city, reflecting industrial waste emissions [1][5]. Data Scope and Sources - The analysis includes over 60,000 samples from more than 5,000 companies, with data sourced from the "China Urban Statistical Yearbook," "China Energy Statistical Yearbook," annual reports of listed companies, and the Wind database [2][3]. - The data processing involved complex methodologies, including interpolation for missing data and the use of software for calculations, which took significant time and effort [3]. Variable Definitions - The GTFP is defined as the ratio of expected outputs (operating income) to inputs (labor, capital, energy) and non-expected outputs (industrial waste emissions) [4][5]. - The GTFP values are adjusted based on the GML index, with 2011 set as the base year for calculations [4]. Results Presentation - The results of the GTFP calculations for various companies are presented in tabular format, showing scores for different years, indicating the productivity changes over time [5][6].

Core Viewpoint - The article discusses the measurement of green total factor productivity (GTFP) for listed companies in China from 2000 to 2024, emphasizing the integration of environmental pollution into the evaluation system and the complexity of data processing involved in this research [1][2][3]. Measurement Methodology - The GTFP is measured using a non-radial SBM index, incorporating labor, capital, and energy inputs, as well as expected and non-expected outputs [1][4]. - Labor input is represented by the number of employees, capital input by the net fixed assets, and energy input is derived from the standard coal consumption adjusted for regional factors [1][4]. - Expected output is measured by the company's operating revenue, while non-expected output is calculated based on the employment ratio and emissions of industrial pollutants [2][5]. Data Scope and Sources - The study includes over 60,000 samples from more than 5,000 companies, with data sourced from various statistical yearbooks and company annual reports [2][3]. - The original data processing involved complex methodologies, including interpolation for missing data and the use of software for calculations [2][3]. Variable Definitions - The explained variable is GTFP, measured using MaxDEA software, which combines both radial and non-radial distance functions [4]. - The input indicators include capital, labor, and energy, while the output indicators consist of expected and non-expected outputs, reflecting the company's performance in terms of productivity and environmental impact [4][5]. Results Overview - The results of the GTFP calculations for various companies are presented, showing the productivity scores over the years, indicating fluctuations and trends in green productivity [6].
