Dynamic evolution and convergence of total factor productivity of rape in China during 1979-2020
Clarifying the development of rape's total factor productivity in China since the Reform and Open-ing-up is a logical starting point to improve the comprehensive production capacity of rape.Based on the input-out-put related data of 11 rape main producing provinces during 1979-2020,this paper analyzes the dynamic evolution and convergence based on the total factor productivity measured by using Global Malmquist index,using kernel den-sity estimation,δ convergence and β convergence,respectively.The results show that,according to the time-series characteristics,China's total factor productivity of rape has achieved certain growth in the midst of dramatic fluctua-tions since the Reform and Opening-up,demonstrating a technology-induced growth pattern,whereas technical effi-ciency does not contribute significantly to it.From the dynamic evolution,the geographical variations in the rise of rape's total factor productivity keep getting smaller.From the perspective of convergence,the overall δ value of total factor productivity of rape is fluctuating and decreasing,and has essentially stabilized around 0.01 since 2012,dis-playing an clear convergence tendency,confirming the existence of δ convergence.The absolute β convergence and conditional β convergence of rape's total factor productivity exist.The convergence model's convergence is still sig-nificant after accounting for the spatial effect,and there is a favorable spatial spillover effect.It suggests counter-measures to support the development of a national rapeseed industrial technology system,execute a regionalized de-velopment plan,and encourage coordinated regional development in order to further increase the total factor produc-tivity of rapeseed.
