科技投入对水产养殖科技园区产出绩效的影响

Influence of Sci-Tech input on the output performance of aquaculture Sci-Tech park

以浙江省水产养殖科技园区为例,应用随机前沿分析方法(SFA)和普通最小二乘法(OLS)分别考察科技投入对水产养殖科技园区核心区不同主体产出绩效的影响以及核心区科技投入对整个园区产出绩效的影响。研究结果表明:1)从核心区主体考察,养殖园区核心主体的产出弹性之和为0.7857,呈现规模报酬递减的特征;2)从不同经营主体考察,养殖场呈现规模报酬递增,规模报酬系数为1.0207,合作社和公司的规模报酬递减,规模报酬系数分别为0.8708和0.4595;3)核心主体的科技带动作用较好,其中,合作社的科技带动作用最好,养殖场次之,而公司则较差。

Taking Zhejiang Aquaculture Sci-Tech Park as an example,the stochastic frontier analysis(SFA)and ordinary least squares(OLS)are used in this study to investigate the impact of Sci-Tech input on the output performance of different aquaculture organizations in the core area of the aquaculture Sci-Tech park and the impact of Sci-Tech input in the core area on the output performance of the entire park.The results show that:1)From the perspective of the aquaculture organizations in core area,the output elasticity of core areas in aquaculture park is 0.7857and shows the characteristics of decreasing returns to scale.2)From the perspective of different aquaculture organizations,the scale returns of farms are increasing,and the scale returns coefficient is 1.0207.The scale returns of cooperatives and companies are decreasing,and the scale returns coefficient is 0.8708and 0.4595,respectively;3)The Sci-Tech function of the core body plays better role in promoting the output performance of aquaculture Sci-Tech park.Among those core bodies,cooperative plays the best role in Sci-Tech driving,followed by farm,while company does the poorest.
