The planning period of "Thirteenth Five-Year Plan" is from 20 16 to 2020, and its time node gives it unusual significance, which is mainly reflected in the following two aspects: (1) The "Thirteenth Five-Year Plan" period is a very crucial five years in China's modernization process. There are three main points: 1 and the Thirteenth Five-Year Plan is the first five-year plan compiled by the new leadership of the CPC Central Committee, which will reflect some important ideas and considerations of the new leadership for future development; 2. The "Thirteenth Five-Year Plan" is an important plan to realize the goal of "two hundred years" put forward by the 18th National Congress. The first century is 202 1, and the thirteenth five-year plan is 2020, which plays a decisive role. 3. The Thirteenth Five-Year Plan is the last five-year plan to achieve the goal of building a well-off society in an all-round way, which is of decisive significance to the smooth realization of the goal. (2) The 13th Five-Year Plan faces a more complicated and changeable domestic and international economic environment. On the one hand, the international economy has fallen into the post-subprime crisis, and the developed economies have entered a new period of slow recovery, but it will take some time to return to the pre-crisis level. The economic development of emerging economies is greatly influenced by the policies of developed countries. Especially when the Federal Reserve announced that it would gradually withdraw from the quantitative easing policy, emerging market countries were hit by a new round of divestment, and there was a great risk that economic growth would fall into a downturn again. On the other hand, after more than 30 years of rapid growth, under the influence of the gradual disappearance of the demographic dividend, the sluggish export market, the environmental damage caused by the traditional extensive growth mode, and the high debt crisis caused by high investment, China has entered a new normal: the two old growth points of export and real estate alternate with the three new growth points of public consumption infrastructure investment, capacity transformation and upgrading, and household consumption, which brings the pain of economic growth; Gradual structural adjustment, such as rising labor wage rate, changing economic geography and increasing the proportion of service industry, has a far-reaching impact on economic development; Due to the lack of motivation in the reform of grass-roots governments and state-owned enterprises, the reform will be difficult to advance. These factors are intertwined, and any topic is a great test for the preparation of the 13 th Five-Year Plan. It is necessary to innovate planning thinking, change planning thinking, strengthen overall planning guidance, and give full play to local autonomy and flexibility to adapt to the more complicated and changeable economic development situation.
