地域産業連関表における経済波及効果のNew Approach
JaLCDOI 10.18926/OER/69003
Title Alternative A New Approach to Economic Ripple Effects in Regional Input-Output Tables
FullText URL oer_057_1_035_050.pdf
Author Nakamura, Ryohei|
Abstract 　本稿では，まず経済波及効果の考え方について，産業連関表を用いたシミュレーションの結果が，しばしば過大評価になっていることを述べる。その理由として，経済波及効果をもたらす前提条件の考え方にしばしば誤解があることを指摘する。域内の居住者の消費はマネーの移転であり，真の経済効果ではない。波及効果とは，本来，所得が増えた結果の追加消費であって，所得が増えない状況では，代替消費や消費の先取りに過ぎないのである。また，一般にいう経済効果とは，売上高の積み上げであって同じマネーが何でも加算されているものであり，付加価値効果すなわち所得効果とは異なる。付加価値効果は，当初の域外から入ってきたマネー以上にはならない。こういった解釈の誤謬をもたらしているのは，大学での産業連関分析の教育が十分でないことも原因の1つであるが，シンクタンクや公的機関などで提供されている波及効果の計算ツールにも問題がある。そこで本稿では，これまで筆者が提唱してきた波及効果プロセスを見える化するモデルを更に精緻化し，イベントなど外生的インパクトが発生した後の事後的な産業連関表を構築する流れに関して実例を用いて説明を行う。特に自給率の変化の効果については，これまでの競争移入型連関表では効果が過大傾向になる問題点を解消するべく，「部分非競争移入型」の投入構造を提案し，新たな分析方法を提案する。

Title Alternative Market Reactions to Earnings Announcements in Profitable and Loss Firm-Quarters: Changes Around the Market Restructuring
FullText URL oer_057_1_021_033.pdf
Author Nakagawa, Toyotaka| Yamanishi, Yuki| Kobayashi, Hiroaki|
Abstract The purpose of this paper is to examine whether the market reaction to earnings announcements in each market segment （prime market segment, standard market segment, and growth market segment） differs between profitable and loss-making firms around the time of market restructuring. We have previously studied market reactions to quarterly earnings announcements in the context of the revision of market segmentation at the Tokyo Stock Exchange. However, we have not studied the differences between profitable firm quarters and loss firm quarters. Therefore, the analysis in this paper focuses on whether the net income attributable to owners of the parent is positive or negative. In the growth market segment, significant differences between profitable and loss-making firms were observed in the results of the analysis.

イノベーションの発生源研究の再検討
JaLCDOI 10.18926/OER/69001
Title Alternative Re-Thinking the Locus of Innovation
FullText URL oer_057_1_001_020.pdf
Author Huang, Qi| Fujii, Daiji|
Abstract 　本論文は，イノベーションの発生源に関する先行研究を振り返り，「いつ」「どこで」「誰によって」イノベーションが生み出されるのかを理論的に考察することを目的とする。考察の結果，「B to B」の文脈においては，イノベーションの発生源が企業ユーザーへ移行するメカニズムとして，取引コスト理論，期待利益仮説，情報粘着性の仮説，企業内部の独自能力（吸収能力），および外部の産業構造（製品アーキテクチャ・エコシステム）といった複数の要素からなる経済的合理性の観点から分析されていることが明らかになった。一方，「B to C」の文脈では，エンドユーザーがイノベーションに向かう動機として，「ニッチ市場に対するメーカーの消極的な対応」「創造的活動の楽しさ」「ユーザーコミュニティとの繋がり」「知識・スキルの向上」など多種多様な要素が存在し，中でも創造的活動の楽しさが根源的な動機づけの1つであると確認された。一方で，イノベーターを突き動かす心理的要因をブラックボックス化したまま放置することは，単なる知的好奇心の問題に留まらず，社会科学としての経営学にとっても重要な問題であると考えられる。今後のイノベーションの発生源研究においては，起業家をはじめとするイノベーター個人の心理的側面にいかに目を向け，創造的活動におけるポジティブな感情が働くメカニズムをイノベーションの発生メカニズムにいかに位置づけるか，その研究アプローチの提示が求められる。
