Abstract:The strategy of “Four Major Economic Plates” is the overall strategy for the regional development of China's 11th and 12th Five-Year Plans. In the period of 12th Five-Year Plan, the state intensively introduced a series of regional planning and guidance, approved the construction and implementation plans of various types of new growing areas. Comprehensive evaluation shows that: (1) the proportions of four major economic plates shake, but the basic pattern has not been changed. In term of economy, the output in the eastern region still consists of half of the country's total, the proportions of central region and western region remain at about 20% respectively, and the proportion of northeast China is still below the 1/10 of the country's total. In term of quality of the people's livelihood, the eastern region is the highest and the people's livelihood index is 6.10 in 2013. The indices are 1.82 and 1.85 in western region and central region, which are relatively low, and the index of northeast region is in between the above major economic plates. (2) Regional development relative gap has been narrowed, but absolute gap is still large. The relative gap among the four major economic plates measured by the variation coefficient, Gini coefficient, and Theil index, the results show a declining trend year by year from 2011. But the absolute gap between eastern region and western region is still increasing, the absolute gap of per capita GDP increases from 25 619 yuan in 2011 to 27 914 yuan in 2014. (3) Urbanization increases rapidly, but land urbanization is faster than population urbanization. The growth rates of urbanization in the central region and western region reach 4.31% and 4.38%, which are higher than the national average. However, the population urbanization rate is generally backward to land urbanization rate of 1-2 percentage points. (4) Resource utilization efficiency has been improved, but wastewater discharge emission and emission intensity are increased as well. Take wastewater emission as an example, the national wastewater emission reach 695.44×10⁴ t in 2013, an increase of 36.25×10⁴ t than the emission of 2011. Among them, the increase of the eastern region is highest, the newly added wastewater emission amount to 12.94×10⁴ t, which accounts for about 35.69% of newly added countrywide wastewater emission. (5) Regional cooperation and opening to the outside world have made great progress. Accordingly, the reasons for the implementation effects of overall regional development strategy are deeply analyzed from the aspects of economic growth driving force, institutional and structural factors, institutional construction, and public awareness of environmental protection. Around the concepts of innovation, coordination, green, open,and sharing, in the terms of implementing innovation-driven strategy, promoting coordinated regional development, perfecting opening layout, and adhering to the green and sharing development, the countermeasures and suggestions are putted forward for overall regional development strategy in 13th Five-Year Plan.
