In the past 2016，world economy recovered slowly，different regions developed more and more unbalanced，international trade and investment continued to languish，and world economic growth still lacked momentum. Due to the US election，trade protectionism has intensified，anti-globalization force has been rising，innovation has not contributed to the science and technology sufficiently，causing to the economic productivity reduced，and the world still being in the “low growth trap”. The leadership of Europe，USA，Japan and other developed countries to the world economic growth is diminishing significantly，India，Mexico and other countries have grown rapidly，but the economy scale is not big enough，thus，Brazil，Russia，Southeast Asia and other countries have not yet come out of the shadow of recession.

2016 is the beginning year of decisive stage to complete the building of a moderately prosperous society，also the crucial year to promote the supply-side reform. In the context of the world economic downturn，the 2016 China’s GDP growth submitted a beautiful transcript，back to the world first. Therefore，the GDP increment rising from the 6.7% growth rate is equal to the 10% growth rate in 2010. From this perspective，China created an economic growth highlight in the background of sluggish world economy. In the past year，the effects of supply-side reform have gradually revealed，as the infrastructure investment，housing and transportation demand becoming unturned，the macroeconomic has been operated smoothly，making a good start to the 13th Five-Year Plan.

In the above background，2016 can be seen as the promising year for the city investment industry. Due to the Circular 43 and the new “Budget Law”，the UDICs responded to the new challenges actively，insisting on reform，increasing investment in infrastructure construction funds by establishing market-oriented financing mechanism under the strong leadership of the municipal government and based on the spirit of “Opinions of the CPC Central Committee and the State Council on Deepening the Reform of Investment and Financing System”. Therefore，many excellent UDICs has tried the infrastructure asset securitization，industrial investment funds，overseas bonds and other new bond financing method to help play the pivotal role in economic growth and maintain the 6.7% economic growth rate.
