    Based upon the standard model of Grilliches (1981), this paper examines the relationship between the intangible asset of energy-saving technologies and stock market value. We furthermore construct the spillover variable of energy-saving technologies for each firm using the definition of technological proximity by Jaffe (1986), and consider their distinctive impact on stock market value. Non-linear estimation using firm-level data of listed Japanese manufacturing firms reveals that intangible assets as a whole are positively associated with market value, although the intangible asset of energy-saving technologies is negatively correlated with market value. In addition, we find that the spillover of energy-saving technologies raises stock market value significantly. These results suggest that developing energy-saving technologies is difficult to appropriate its potential private rate of return, and the research and development (R&D) for energy-saving technologies is underinvested and socially insufficient. Policy implications are also discussed.
