title: 建筑企业上市公司2000-2023年碳排放数据与数字化转型、公司财务数据

description: The research data in this article comes from the data of Chinese A-share listed companies from 2000 to 2023; The annual reports of relevant companies are obtained from the official websites of the Shenzhen and Shanghai Stock Exchanges; The relevant data of listed companies comes from the CSMAR database of Guotai An. At the same time, this article conducts a 1% truncation process on non ratio continuous variables to reduce the impact of outliers. (1) Due to the lack of mandatory disclosure of carbon emission data by the Chinese government, there is currently a lack of micro level data on corporate carbon emissions. This study adopted the method of Chapple et al. (2013) to indirectly measure the carbon dioxide emissions of enterprises. Due to the lack of 23 years of carbon emission data, this study borrowed the ARIMA-BP prediction method from Hu Jianbo (2013) and Zhao SL et al. (2024) to fill in the predictions. (2) The degree of digital transformation of listed companies (Digital) The measurement methods for digital transformation of companies are relatively mature, and the measurement method adopts text analysis. This article first constructs numbers Keyword table for transformation; Then use Python software to match the vocabulary with the text of the annual report of the listed company, and use Jieba's method The module can calculate the frequency of relevant keywords appearing in the annual report documents of listed companies; Finally, add 1 to the frequency of the word and perform logarithmic processing Obtain indicators for enterprise digital transformation. Please refer to Wu Fei's (2021) approach (Managing the World) for specific details. (3) Control variables. This study includes enterprise level indicators as control variables: property rights nature of enterprises (SOE), with state-owned enterprises set to 0 and private enterprises set to 0 1) For operating enterprises, the board size (logarithm of the number of board members), the logarithm of the age of the enterprise (age), and the assets and liabilities Rate (lev), return on equity (roe), operating cash flow (CF), sales growth rate (growth), net profit growth rate (gprofit) Proportion of tangible assets (tangibi), proportion of independent directors (indep), proportion of the largest shareholder's shareholding (top 1) The dual role of chairman and general manager, and the nature of property rights (SOE). This study was supported by the Key Support Project for College Students' Innovation and Entrepreneurship in Hunan Province - Research on the Factors and Mechanisms of Digital Transformation of Construction Enterprises in the Digital Economy (S202411532001)
