The shortage of domestic investment and surging excessive savings are always problems that give the government a headache. According to Executive Yuan statistics, Taiwan's net national savings totalled NT$3.64 trillion (US$112.22 billion) in 2009. While the net domestic investments only reached NT$2.18 trillion that year, the country saw NT$1.46 trillion in excessive savings, accounting for 11.28 percent of the gross national product (GNP). In 2010, private investment rebounded, but national savings also expanded to break the level of NT$4 trillion. As a result, excessive savings this year will fall only slightly to NT$1.28 trillion. The percentage of excessive savings to GNP in 2010 is expected to reach a high level of 9.42 percent. These high savings are the cause of a flood of idle funds in the country. Taiwan people are not short of money, but investment opportunities must be created by the government in order that idle funds can flow into national construction projects. To tackle the problem, Christina Liu, the new chairwoman of the Council for Economic Planning and Development, has proposed bringing in the 'public-private partnership (PPP) ' investment model from overseas. However, it is doubtful that the model will be successfully implemented in the country, given the disputes that have arisen in the wake of the major national construction projects based on the 'build, operate, transfer (BOT) ' model, including the High-Speed Railway. To successfully copy the PPP model in Taiwan, mutual trust needs to be promoted between the government and people, while strict regulations must be set forth and a political environment that will help the investment model must be adopted.
