海洋科技创新TFP增长的差异与收敛
|
摘要
文章运用Malmquist-DEA指数方法考察中国沿海省、市、自治区2006—2015年海洋科技创新全要素生产率(TFP)变化情况,并将其分解为TEC、TC、PC及SE等4个指标用以分析海洋科技创新TFP增长的内在原因,并对沿海各地区海洋科技创新TFP增长的差异进行收敛检验。研究发现:(1)海洋科技创新TFP呈现总体增长趋势,但总体规模处于规模报酬递减阶段。(2)在观察期内,沿海地区TEC、PC和SE这3个指数指标走势基本相同,较为稳定,都在1.000这条水平线附近做微小波动,对海洋科技创新TFP的增长影响较小。海洋科技创新TC是海洋科技创新TFP增长的决定性因素。(3)海洋科技创新TFP增长存在α收敛和绝对β收敛,沿海地区海洋科技创新TFP之间存在"追赶效应"。
In this paper,Malmquist-DEA index method was used to investigate the changes of total factor productivity(TFP)of marine science and technology innovation in 11 coastal provinces(municipalities and autonomous regions)of China from 2006 to 2015,and it was decomposed into four indicators:TEC,TC,PC and SE.It was used to analyze the internal causes of the growth of marine technology innovation TFP,and to test the convergence of the growth of marine science and technology innovation TFP in coastal areas.The study found that:(1)The marine technology innovation TFP showed an overall growth trend,but the overall scale was in the stage of diminishing returns to scale.(2)During the observation period,the three index indicators of TEC,PC and SE in coastal areas were basically the same and relatively stable.They all made small fluctua-tions around the 1.000 level,which had little impact on the growth of marine technology innovation TFP.Marine technology innovation TC was the decisive factor for the growth of marine technology innovation TFP.(3)Ocean technology innovation TFP growth hadαconvergence and absoluteβconvergence,and there was a "catch-up effect"between marine technology innovation TFPs in coastal areas.
