| "The poor can be alone,and the good can help the world" has been our country’s noble code of reference since ancient times,and charitable donations have played a pivotal role in modern society.The fourth,fifth and plenary sessions of the 19 th CPC Central Committee stressed the importance of the third distribution,developing philanthropy,and reducing the income gap between the rich and the poor.The 10 th meeting of the Central Finance and Economics Commission in 2021 is the first time that charitable donations are clearly defined as "basic institutional arrangements",which have become an important means and basic institutional arrangement for adjusting income distribution and achieving common prosperity.Due to the importance attached by Chinese government departments to charitable donations and the improvement of public awareness of donations,the level of charitable donations in my country has steadily improved.Among them,enterprises are the main force of charitable donations,and the proportion of corporate charitable donations has always exceeded half.However,my country’s charitable donations are still far from international leading standards,and it is necessary to further improve relevant preferential policies to promote corporate charitable donations.Based on the above background,This paper takes the effect of preferential income tax policy on charitable donation as the research object,draws conclusions and puts forward suggestions through mathematical analysis.content is as follows:Theoretical analysis section.Based on the definition of basic concepts such as preferential income tax policies and corporate charitable donations,integrating the third distribution theory and corporate social responsibility theory,and based on the assumption of the goal of maximizing utility,create a theoretical model of the influencing factors of charitable giving,and then analyze how preferential policies affect charitable giving Mathematical model analysis results show that preferential income tax policies do affect corporate charitable donations.Specifically,pre-tax deduction is the most important factor.The proportion of pre-tax deduction and charitable donations are a positive incentive.The incentive effect is more significant.Analyze the current state of corporate charitable giving.First introduce the preferential policy of charitable donation and then point out the problems in them.Then the overall situation of corporate charitable donations and the charitable donation behaviors of different industries,different profit levels,and different types of enterprises are systematically analyzed,in order to explore corporate charitable donation behaviors possible influencing factors.The results show that,as the main force of charitable donations in my country,the scale of charitable donations of enterprises will greatly affect the overall scale of charitable donations in my country,while private enterprises are the main force of charitable donations,and their share of charitable donations has remained at about half.And private enterprises are more sensitive to tax incentives than other enterprises.Large-scale and profitable enterprises have responded strongly to policy adjustments.In addition,the level of charitable donations of enterprises in the manufacturing,real estate,financial and other industries is relatively high.Empirical analysis section.Firstly,based on the theoretical research assumptions of this paper and the status quo of corporate charitable donations,the variable selection and model setting are completed,and the empirical test is completed with the data of listed companies from 2015 to 2019.The impact of charitable giving.Empirical research shows that the above policy adjustments have indeed improved the level of charitable donations and strengthened the willingness to donate.And through empirical analysis,it is found that different scale enterprises,enterprises with different profitability and enterprises with different property rights have different degrees of response to policy changes.Finally,according to the above,put forward policy suggestions from the perspectives of policy improvement,policy management and supervision,and other corresponding supporting measures. |
