This study employs imprinting theory, cultural capital theory, and upper echelon theory to investigate the influence of the rural upbringing of board chairpersons on corporate R&D (Research and Development) and advertising expenditures, as well as the moderating impact of the chairperson’s marketing and financial experience in the competitive market environment. A binary dataset was compiled, comprising 1058 Chinese listed companies and 5434 board chairpersons as samples. Through multiple regression analysis, we established a link between board chairpersons’ rural backgrounds and short-term marketing expenditures. The findings indicate that chairpersons’ rural upbringing negatively affects R&D and advertising expenditures. Additionally, marketing experience exerts a negative moderating influence on R&D expenditure, whereas financial experience does not exhibit a significant moderating effect. Furthermore, the market growth rate positively moderates the relationship between the chairman’s rural background and R&D as well as advertising expenditures. This suggests that the external competitive environment may attenuate the conservative imprint associated with a rural upbringing. This study departs from the conventional paradigm of understanding short-term spending based solely on economic incentives, incorporating non-economic factors rooted in individual cognition and values. It introduces a fresh perspective to the examination of myopic spending and contributes to the exploration of how birthplace impacts corporate decision making. These findings offer a deeper comprehension of how the background of chairpersons influences firms’ decision-making behavior, providing valuable insights for top executives in crafting strategies and making informed decisions.
