| Outline of Final Research Achievements |
Using establishment-level micro data, we estimate the productivity of companies that manufacture transportation equipment and find that the factor that contributes to growth is related to innovations. Moreover, we represent these results on maps with the addresses of each establishment. It becomes clear that the establishments that have higher innovation effects on dynamics tend to construct industrial agglomerations.
To explore knowledge networks related to innovations from linkage of knowledge combinations regarding automobile parts, we measure the knowledge relatedness between automobile parts by focusing on similarities in technologies embedded in products. We find that the density of relatedness differ according to the part type. This result confirms that the parts that have high-density relatedness are located on the core or hub of the knowledge networks and are next-generation parts. It is suggested that new parts emerge when new knowledge is connected to the existing network.

従来，地域経済成長の計測には事前に産業や地域が集計されたデータを利用してきたが，本研究は事業所の個票データを用いることにより，実際の生産活動単位である事業所レベルでの生産性や知識ネットワークを計測した。また，分析結果を地図上に可視化したことにより，行政境界にとらわれることなく実データにもとづく成長傾向が似ている地域や産業集積を検出した。本研究は，産業集積におけるイノベーションの波及過程を定量的に評価する手法を提案し，ミクロ的側面から解明した点において学術的意義が大きい。研究成果は，実践が先行してきた産業クラスター関連政策のこれまでの評価や今後の立案に際し，より実証的根拠を持つ情報を提供する。
