The Spatial Agglomeration And Its Spillover Effect Of The Fishery Economy In The Pearl River Delta Cities

As we all know, the21st century is the century of the sea, and with the warmingof "ocean heat", ocean-economic-environmental and related issues have become thefocus of policy makers and academics. Fishery is an important part of marine industry,and the development of it has great significance of agriculture, marine industry andthe national economic. In the period of “Twelve Five”, the “blue fishing” has been thestrategic focus of adjusting and optimizing the structure of fisheries. In this paper, inorder to study the spatial clustering and spatial spillover effects of fisheries economicin the Pearl River Delta cities, the “geospatial” has been introduced to the analysis ofregional fisheries economics. Firstly, in order to analysis the phenomena of spatialclustering about the fisheries economic in the Pearl River Delta cities, we selected theindicator of fisheries economic output and the mean of exploratory spatial dataanalysis (ESDA).Secondly, we researched the dynamic mechanism of the spatialclustering and spatial spillover effects. Lastly, we select the variables as fisheries fixedcapital investment, labor fisheries, fisheries technologies, aquaculture area and fisherystructure to make an empirical research about spatial effects, influences factors anddifferences. Thus, for promoting economic growth in fisheries, we can give a deepstudy about effects of the factor. Through these studies, we have several findings. First,the spatial distribution pattern of the development of the fisheries economic in thePearl River Delta cities has a significant spatial clustering phenomenon. On one hand,the spatial correlation of fisheries economics shows the law of “distance decay”. Onthe other hand, it shows the trend of the degree of concentration is increasing in thetime dimension. Second, with the analysis of local spatial autocorrelation, we foundthat there were four types of spatial interaction model in the development of fisherieseconomics in the Pearl River Delta cities. Among the four types, there was low-lowgathering area and this area was likely to fall into the “poverty trap”. The economicgrowth rate of fisheries in Shenzhen and Dongguan has gradually influenced Huizhou.The economic growth rate of fisheries in Huizhou trends to a low growth. Third, thespatial error variables are important factors for the fisheries economic growth. Thespatial spillover effects caused by the spatial clustering have a significant role inpromoting the growth of fisheries economics. The spatial spillover effects werereflected through space gathering and the factors themselves also have a strong spatialcorrelation. Four, the development of fisheries economics in the Pearl River Delta cities are different. Besides the factors of the spatial clustering and spatial spillovereffects have some influence, there are still some factors such as fisheries fixed capitalinvestment, labor fisheries, aquaculture and fisheries industry. They have a significantpositive correlation with the fisheries economics in the Pearl River Delta cities.
