摘　　要：基于柯布-道格拉斯生产函数和威廉姆森假说分别构建线性模型和非线性模型,利用广西14个地级市2003-2016年的面板数据进行实证检验,发现不考虑非线性影响时,产业协同集聚均值与广西经济增长负相关,即均值水平下的产业协同集聚抑制了广西经济增长;考虑非线性影响后发现,产业协同集聚对广西经济增长的影响表现为倒"U"形关系,即产业协同集聚最初能促进广西经济增长,但超过一定阈值后会抑制广西经济增长,从而验证了威廉姆森假说在广西产业协同集聚中的适用性.进一步利用上述非线性关系构建门槛模型进行实证检验,发现广西产业协同集聚作用于经济增长时存在随生产性服务业集聚度变化而变化的单一门槛效应,相对于跨越门槛值前,生产性服务业集聚度越过门槛值0.5867的产业协同集聚对经济增长的抑制力已大幅下降.Based on the Cobb-Douglas production function and the Williamson hypothesis,a linear model and a nonlinear model were constructed respectively.By using the panel data of 14 prefecture-level cities in Guangxi from 2003 to 2016,this paper finds that when the nonlinear influence is not considered,the mean value of industrial co-agglomeration is negatively correlated with the economic growth of Guangxi,that is,the industrial co-agglomeration under the mean level inhibits the economic growth of Guangxi.After considering the nonlinear influence,it is found that the impact of industrial co-agglomeration on the economic growth of Guangxi is an inverted U-shaped relationship,that is,industrial co-agglomeration can initially promote Guangxi’s economic growth,but it will inhibit Guangxi’s economic growth once it exceeds a certain threshold.Thus this conclusion verifies the applicability of the Williamson hypothesis in the industrial co-agglomeration of Guangxi.Further,using the above-mentioned nonlinear relationship to construct the threshold model for empirical test,it is found that the industrial co-agglomeration of Guangxi has a single threshold effect that economic growth changes with the growth of the producer service industries’agglomeration.Compared with the threshold value before the production service industries’agglomeration,the suppression of economic growth from the industrial co-agglomeration has fallen sharply with a threshold of more than 0.5867.
