Research on the Technological Innovation Efficiency of China’s Strategic Emerging Industries Based on SBM: NDEA Model and Big Data

Table 1

Assessment indicator system of two-stage technological innovation efficiency of strategic emerging industries.

Initial innovation input (X)	Fund input	R&D internal expenditure: billion yuan
		New product development expenditure: billion yuan
	Personnel input	Full-time equivalent of R&D personnel:
Technological output (MY)	Knowledge innovation	Patent application quantity: ( or )
		Effective patent application: ( or )
Innovation resource input (MX)	Technological commercialization	Expenditure on technological transformation: yuan
		Number of scientific and technical personnel
Final output (Y)	Economic benefits	Sales of new products: yuan
		Exports: yuan

and refer to input and output indicators of knowledge innovation at note 1; similarly, and refer to input and output indicators of commercialization of scientific and technological achievements at node 2. At the same time, because technological output is both the output index of the first stage and the input index of the second stage, it has two marks.
