我国产业集群研究现状及理论述评 总被引:20,自引:0,他引:20
20世纪90年代以来,关于产业集群的论述已成为区域经济学、产业经济学和经济地理学等学科的重要研究内容,这一方面与国际学术动态有关,另一方面也与我国不同形式的产业集群的出现有关.我国学者对产业集群进行了大量研究,包括产业集群的定义和分类、产业集群的形成与培育、产业集群与区域竞争力的提升、产业集群与创新网络等方面.从整体来看,我国运用产业集群理论成功地解释了一些现象,但是也存在诸多问题,今后应加强对产业集群形成机理的研究,实现定性与定量相结合、理论与实践相结合,以指导我国产业布局实践. 相似文献

黑龙江的经济发展相对处于全国落后水平,但长期以来的发展事实已说明刻意模仿和单纯利用自身资源发展相关产业无法实现经济赶超。从输出基础理论的角度,分析发展较快的省份产业选择及其产业相关度情况,以此为依据选择黑龙江最具有经济带动性的产业并根据相应的产业关联形式建立相应的产业集群,突破被动承接附加价值最低端的产业从而长期发展缓慢,改变产业体系散乱缺乏有效竞争力的现状,转变依赖资源输出的经济发展模式为发展高附加值的以制造业为主的产业集群,建立相对高效的生产体系,真正利用自身的资源优势,从而实现黑龙江经济的全面振兴。 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 相似文献

The increase in the number of tourists visiting a coast is desired by most of the countries for economic reasons. However, this increase in tourism may cause pollution of the sea. This can be only avoided by proper planning and by predicting the carrying capacity of the coast in terms of sea pollution. This is especially important for developing countries where part of the wastewater is discharged without any treatment into the sea.In the present study the beaches were classified according to their use — and consequently the amount of waste discharged into the sea — into four groups: (1) coasts that are used only for swimming and recreational purposes; (2) coasts used simultaneously for dwelling, swimming, and recreational purposes; (3) coasts along which only dwellings exist; and (4) natural and man-made harbors, i.e., coasts used as shelters. During the survey,40,320 observations were made between December 1985 and February 1988 to determine the effect of the number of tourists on seawater quality. The results obtained were analyzed by a multilinear regression program to obtain an empirical equation giving the extent of the sea pollution in terms of coliform concentration as a function of population density and some other environmental factors.The equations derived in this study enable the determination of the carrying capacity of a beach in terms of pollution as well as the expected degree of pollution corresponding to a given population density. Furthermore, it allows the prediction of the extra carrying capacity that can be obtained by improving the waste-disposal conditions. 相似文献
