As China entered into a new era of development, the primary contradiction facing Chinese society has also evolved. It is important for both scholars and policymakers to review the characteristics of China's economy in its present stage in accordance with economic principles-principles that reflect every aspect of economic and social life and macroeconomic regulation. In this paper, we attempt to unravel the characteristics of China's new era from three perspectives-historical materialism, dialectic materialism and epistemology, and in light of economic principles at the three levels of resource factors, modes of production and regulation of resource allocation. Based on these perspectives, this paper further identifies the characteristics of China's new era from nine aspects, including globalization, modernization, the primary stage of socialism, new development concepts, supply-side reforms, the guideline of seeking steady progress, the mentality of scope, bottomline mindset and strategic composure. From the three different levels, this paper summarizes and applies economic principles to propose solutions to the problems and challenges facing China in the new era. The findings of the paper are also relevant to implementation of the guidelines CPC Central Committee General Secretary Xi Jinping noted in his report to the 19 th CPC National Congress. 展开更多
