摘要

This paper examines the price of financial trade-offs of research and development (R&D) expenditures in terms of their impact on firm profitability, based on a comprehensive longitudinal sample of 619,854 firm-year observations from 1951 to 2024, obtained from Compustat. Although R&D is widely recognized as a long-term driver of innovation and firm value, its short-run cost implications remain contested. Our findings reveal a significant negative relationship between R&D outlay and short-term profitability, reflecting the substantial up-front financial burden of innovation. However, firm-specific factors—such as employee size, total assets, market capitalization, and long-term debt—moderate this effect, indicating that larger and better-capitalized firms are more capable of absorbing innovation costs. Using a range of econometric techniques—including OLS, fixed effects, Gaussian GLM, interaction and quadratic specifications, and dynamic panel estimation via Arellano-Bond GMM—we establish robust evidence for these dynamics. Further analysis shows that while R&D may depress accounting-based profitability in the short term, it enhances market valuation, suggesting that capital markets reward firms for signaling innovation intent. By synthesizing insights from the Resource-Based View, Signaling Theory, and Capital Structure Theory, this research contributes to understanding how internal capabilities and financial strategies shape the economic returns of innovation investments. The results have important implications for innovation policy and strategic financial management in knowledge-based economies.
