Digitalization and intelligent transformation have become the general trend of global economic development in the Data-intelligence era，and China’s achievements in digital economy development have attracted worldwide attention，with an overall scale ranking second in the world. Data-intelligence has subverted traditional industries，reshaped the professional field and human ability structure，and the demand for digital talents in various fields is exploding. China urgently needs to accelerate the construction of digital talents，use higher quality and better structured human resources to help generate new productive forces，hedge against risk factors such as reduced labor force，deepening aging，and structural employment contradictions，and support high-quality and sustainable development of the digital economy. China’s digital economy has the largest employment scale in the world，but it also faces prominent difficulties such as total shortage，uneven distribution of industries and regions，and insufficient supply capacity. The key to breaking through the bottleneck of digital talent development is to further deepen the reform of the talent development system and mechanism，and establish the advantages of the talent system in the Data-intelligence era. Based on the above situation，in view of the main opportunities and challenges faced by the talent development in the Data-intelligence era，and starting from the intelligent characteristics，construction principles and construction contents of the talent system，this paper puts forward the ideas of talent system and mechanism reform in line with China’s national conditions and the law of talent development.
