For these reasons, determining whether low investment is a cause or a consequence of slow growth is not as easy as it may seem. Taking push and pull factors into account, DIW, the German economic institute, reckons that the investment gap is real; for the eurozone, it puts the gap at about 2% of GDP, or €200 billion.
出于这些原因，确定低投资是低增长的原因还是结构并不像表面看起来那么简单。德国经济研究所DIW在考虑了推动和拖累因素后认为，投资缺口是实实在在的；对欧元区来说，这一缺口大约为GDP的2%，或2,000亿欧元。这是个很大的数字，意味着应该为此采取政策动作。
