工业企业核心与非核心行业发明专利生产的边际产出、产出弹性和规模报酬比较OA

Invention patents are the representative variables of new quality productive forces,in view of this,ranking industries by their share of invention patents is an ideal indicator for identifying core sectors in invention patent production.Among the 38 industrial sectors with statistical data in China,the top 10 industries accounted for approximately 80％of the total number of invention patents produced,they are the core sectors of invention patent production.This paper empirically analyzes the data from 38 industrial sectors by constructing a theoretical multiple linear model and a C-D production function model.The findings reveal that:In core sectors,the marginal output and output elasticity of capital in invention patent production are greater than those in non-core sectors;for every additional 100 million yuan in capital investment in core industries,the average marginal output increases by 19.82 invention patents,moreover,the increased capital investment results in output elasticity that is 0.411 2 points higher than that of non-core industries on average;In non-core sectors,the marginal output and output elasticity of labor in invention patent production are greater than those in core sectors,for every 10 000 additional science and technology professionals,the average number of invention patents will increase by 628.13;Besides,the returns to scale of labor and capital in invention patent production are greater in core sectors than in non-core sectors.Consequently,it is recommended to prioritize support for core patent sectors,increasing R&D capital investment to enhance capital deepening,and simultaneously encouraging non-core sectors to expand their R&D personnel.
