【摘要】：正近期美國經(jīng)濟(jì)活力下降的問題引起學(xué)界關(guān)注,該問題主要表現(xiàn)為新公司創(chuàng)立速度降低、上市公司數(shù)量回落、中小企業(yè)成長潛力縮小、公司出現(xiàn)老齡化等等,此外勞動力市場流動性下降也與上述現(xiàn)象有關(guān)。經(jīng)濟(jì)活力下降并非短期周期性現(xiàn)象,而是各種深層次因素作用的結(jié)果。它意味著大公司市場主導(dǎo)地位有所增強(qiáng),新企業(yè)處于更不利的競爭位置;它對技術(shù)創(chuàng)新的影響有些爭議,但新老企業(yè)間"創(chuàng)造性破壞"效應(yīng)減弱整體上不利于技術(shù)創(chuàng)新;經(jīng)濟(jì)活力下降也會影響美國的中長期經(jīng)濟(jì)增長后勁。
[Abstract]:The recent decline in economic vitality in the United States has attracted the attention of the academic community. This problem is mainly manifested in the decline in the speed of the establishment of new companies, the decline in the number of listed companies, the shrinking growth potential of small and medium-sized enterprises, the aging of companies, and so on. In addition, the decline in labour market liquidity is also related to these phenomena. The decline in economic vitality is not a short-term cyclical phenomenon, but the result of various deep-level factors. It means that the dominant position of large companies in the market has been strengthened and the new enterprises are in a more disadvantageous position of competition, its influence on technological innovation is somewhat controversial, but the "creative destruction" effect between new and old enterprises is not conducive to technological innovation as a whole. The decline in economic activity will also affect the U. S. medium-and-long-term economic growth momentum.
