基于环保产业的销售费用和研发投入对经营绩效影响研究

Research on the Influence of Sales Expenses and R&D Investment on Business Performance Based on Environmental Protection Industry

摘要: 本文选取了2019~2022年沪深A股及创业板环保企业为初始研究样本，通过对样品进行筛选，排除财务数据不完整和经营情况不稳定的环保企业，最终获得60家环保企业数据共240个。运用Stata16.0软件进行数据F检验、Hausman检验，最终选择固定效应模型进行面板数据回归分析，研究结果表明环保企业销售费用率和销售费用增长率均未与当期主营业务利润率呈现显著相关性，研发投入强度与当期主营业务利润率未显著相关而对下期企业主营业务利润率正相关，进而对环保企业经营提出可信性建议。

Abstract: In this paper, 2019~2022 Shanghai and Shenzhen A-share and GEM environmental protection enterprises were selected as the initial research samples. By screening the samples, the environmental protection enterprises with incomplete financial data and unstable operating conditions were excluded, and finally 240 data of 60 environmental protection enterprises were obtained. Stata16.0 software is used for data F test and Hausman test, and finally fixed effect model is selected for panel data regression analysis. The research results show that the sales expense rate and sales expense growth rate of environmental protection enterprises are not significantly correlated with the current operating profit rate, while the R&D investment intensity is not significantly correlated with the current operating profit rate, but positively correlated with the next operating profit rate of enterprises, and then credibility suggestions are put forward for environmental protection enterprises.
