研究成果の概要（和文）本研究の主な目的は、発展途上国におけるグリーンイノベーションの源泉を解明することである。特に本研究は発展途上国における過去のグリーン輸出や技術構造が、グリーンイノベーションの創出にどの程度貢献するのか、また先進国の事例との相違点を研究する。本研
究の分析結果は、２０２４年６月の R&D Management 2024 学会発表に受理された（査読付き）。また、この研究のデータと問題意識を活用して、派生した研究は国際論文に２０２４年１月掲載された[1]。本研究の学問的成果は、グリーンイノベーションの源泉としてのグリーン輸出生産の役割や発展途上国の実証結果を提供することにより、これらのリサーチギャップを埋めることに貢献することである。本研究は、雇用機会と経済成長 (SDG8) および産業とイノベーション (SDG 9) と密接に関連している。

研究成果の学術的意義や社会的意義
This study is closely linked with job opportunities and economic growth (SDG 8)
and industry and innovation (SDG 9). Promotion of green, sustainable innovation
along with economic/industrial growth through green innovation are key
interests of developing economies. This study suggests an effective way to set
target industries for sustainable innovation among developing countries, bystudying the past and present production and knowledge structures.
1. 研究の背景
Most studies on green innovation are focused on the cases of developedcountries. Among the few studies on developing countries, only a limited
number highlights the importance of production in innovation. This study fills
the research gap by 1) bringing green export production as a potential sourceof green innovation, and 2) the providing an empirical evidence fromdeveloping countries.
2. 研究の目的
The main purpose of this study is to elucidate the sources of green innovation
among the developing economies. Specifically, this study studies whether andto what extent the past green export and knowledge structures contributeto spurring green innovation among developing countries, and how theydiffer from the patterns of developed countries.
3. 研究の方法
In order to answer these questions, this study constructs a panel dataset ofexport production and patent grants covering around 80 countries (includingboth developing and developed countries) from 1980 to 2020. This dataset
contains the export data from the United Nations Conference on Trade andDevelopment (UNCTAD), patent data from United States Patent andTrademark Office (USPTO), and Algorithmic Links with Probabilities (ALP) tolink the two datasets. It uses econometric methods to test the causal
relationship between the current production/knowledge with two types of
future green innovation, and network analysis to illustrate the green export
and knowledge structures of selected developing countries.

4. 研究成果
The results confirm the two hypotheses suggested in this study. First,emergence of new green export product in developing countries is less likely
to depend on their past green knowledge structures. Second, emergence of
new green technology in developing countries is likely to depend on their pastgreen export production structures. These results suggest that developing
economies should focus on innovation in the green sectors that they
currently have comparative advantage in production. Also, the results imply
that there is an alternative path-dependence of innovation, from production
to innovation.
This study is expected to be presented in international conferences in 2024
(accepted to R&D Management 2024, Stockholm, June 2024), and received
comments from two reviewers.
Also, applying the dataset collected and measures to test the pathdependence among nations in this study, an additional study [1] on pathdependent capability evolution among European countries has beencompleted. This has been published in Baltic Journal of Economics in 2024.
