シュンペーター経済動学モデルによるイノベーションの分析 Innovation Process Analysis by SchumPeterian Dynamics Model シュンペーター ケイザイ ドウガク モデル ニ ヨル イノベーション ノ ブンセキ 富田, 輝博 Schumpeterian dynamics evolutionary economics Nelson-Winter model innovation imitation This paper examines the Schumpeterian dynamics of economic change and analyses innovation and imitation process of industry. Schumpeter stresses non equilibrium aspects of capitalist development. The creative destruction which incessantly revolutionizes the economic structure from within, incessantly destroying the old one, incessantly creating a new one is one of the fundamental mechanisms of capitalist economic development. We call this theory as evolutionary economics contrasted to neoclassical economics. 　Nelson and Winter presented and promoted their idea of an evolutionary prosess by means of their models and simulation results. 　Following introduction section 2 surveys the Nelson-Winter model of Schumpeterian competition. The third section simulates innovation and imitation processes of industry by Nelson-Winter model with Maple V. 4 language. In the simulation of NW model, we analysed the behavior of productivity, output, market share and profit rate of 4 firms and price, and output of industry for 20 periods( 5 years). 　In conclusion, we find Nelson-Winter model explores the process of Schumpeterian competition dynamically and simulate the behavior of innovation and imitation process of firms. But, we need to extend the model such as satisfying behavior of firms, product innovation and entry and exit of industry and to articulate policy implications by simulations. 文教大学 1996-01-01 jpn departmental bulletin paper VoR https://bunkyo.repo.nii.ac.jp/records/3468 03893367 情報研究 Information and Communication Studies 17 171 182 https://bunkyo.repo.nii.ac.jp/record/3468/files/BKSJ170008.pdf application/pdf 757.5 kB 2018-03-24
