本文以Brander和Lewis的资本结构产业组织理论为基础,结合资本市场与产品市场,分析了企业负债与广告投资、R&D投资之间的关系.通过模型推导提出理论命题,并运用我国沪深两市A股上市公司数据进行验证得到相关结论.研究结果显示负债对企业广告投入存在刺激作用而对R&D投资存在抑制效应.企业广告投入与R&D投入行为存在明显的行业差异,制造业企业两种投入相对均衡,非制造业企业通常偏好于二者之一.企业广告与R&D投入之间相互影响,制造业两种投资之间存在互补关系,而非制造业两种投资之间存在替代关系.负债对企业广告与R&D投资行为的影响存在差异,并且不同债务类型的影响同样存在差异.本研究可进一步促进资本结构产业组织理论的发展,同时为企业改善广告与R&D投资策略提供理论和经验依据.
Advertising and R&D Innovation under Debt Constraint
Combining output market with capital market and based on the capital structure industrial organization theory,how debt affects firm's advertising and R&D investment behavior along with what are the relationships between advertising and R&D innovation are studied in this paper.After theoretical and empirical analyzing,the following conclusions are achieved.Firstly,debt increases firm's advertising but inhibits R&D investment and different kinds of debts have different effects.Besides,firm's advertising and RD behavior are different between different industries and manufacturing firms invest both of them while non-manufacturing firms only perform one of them.Moreover,advertising investment is complementary with R&D investment in manufacturing firms but it is competitive with RD innovation in non-manufacturing firms.This study is valuable for the improving of capital structure industrial organization theory and helpful for firm's advertising as well as RD competition strategy.
