As the reason of the increase of dependency on "Induction of Ripple Effect" due to "Foreign Demand", it can be guessed that decline of composition ratio of "Domestic Demand" due to increase of "Foreign Demand" and weakening of "Ripple Effect" of "Domestic Demand" due to "Ripple Effect" become to be prone to flow out by increase of imports are united. この「外需」による「波及効果の誘発」への依存が増加した理由として、「外需」の増加に伴う「内需」の構成比の減少と、輸入の増加により「波及効果」が流出しやすくなったことによる「内需」の「波及効果」の弱体化が合わさったことが考えられる。 - 経済産業省
