工业用地是区域土地利用的重要组成部分,也是影响区域土地集约利用的关键因素。以江苏省阜宁经济开发区为例,从系统集约度及协调度出发,研究区域各工业行业的集约度及协调度,结果显示：阜宁经济开发区工业用地整体处于低效利用水平,工业土地利用协调性处于轻度失调状态;主导行业机械机电业用地的集约性、协调性都较差;电子电工、纺织服装及食品饮料业用地规模较大且集约性、协调性超过区域平均水平,可作为阜宁开发区未来重点扶持发展的行业。 相似文献

土地是民生之本,发展之基。开发区作为改革开放的先行区域,所发挥的集聚效应、示范效应和扩散效应,在促进经济高速发展中发挥了举足轻重的作用,已经成为产业升级、区域发展的推动器和科技创新基地。但在开发区土地利用中,重扩张轻挖潜、重规模轻效率、重引资轻规划等问题仍未得到有效解决。改变开发区外延扩张,用地粗放的局面,开展开发区土地集约利用评价,对促进开发区用地挖潜,提高开发区用地管理水平．建立健全开发区土地节约集约利用考核制度与长效机制,增强土地参与宏观调控的能力,构建资源节约型社会具有重要意义。 相似文献

This study evaluates the environmental efficiency of industrial sectors of Chinese major cities. The multi-directional efficiency analysis (MEA) approach is utilized for evaluation; thus, both the integrated MEA efficiency levels and the efficiency patterns, which are represented by the variable-specific MEA efficiency according to each type of the industrial pollutant emission or discharge, of Chinese major city are detected. In addition, the industrial energy conservation and pollutant reduction potentials are measured, and the relationship between environmental pressure and income is explored at the regional level of China. The main findings include the following: (1) The MEA environmental efficiency increases in the economically less developed cities were faster than the cities in the well-developed region, which indicates that the inequitable nationwide industrial developments of Chinese cities have started to alleviate. (2) Although some Chinese cities show similar environmental efficiency levels, the undesirable output variable-specific efficiency patterns of these cities are diversified, and according to the variable-specific efficiency, the most possible efficiency increase potential of each Chinese major city can be identified. (3) An N-shaped environmental Kuznets curve exists in the industrial sectors of Chinese major cities. (4) Different Chinese cities should have different industrial pollutant reduction priorities: East China cities should pay more attention to their industrial waste gas emissions and industrial waste water discharges, while west China cities should mainly focus on their industrial soot and dust emissions, and solid waste discharges. 相似文献

采用投入产出分析方法, 以黑河流域中游的张掖市为例, 将传统的价值型投入产出表和水资源利用的实物型投入产出表相结合, 构建了混合型水资源投入产出表, 并估算了张掖市各行业的直接用水系数、 用水乘数、 直接产出系数、 产出乘数以及综合用水特性. 结果表明: 张掖市种植业、 畜牧业和其他农业的用水效益和用水效率远低于其他行业, 直接耗用水程度均高, 而直接产出一般. 张掖市过度依赖种植业的产业结构特征造成该地区对水资源的过度依赖. 因此, 调整产业结构, 实施高效的节水措施, 适当降低农业尤其是种植业在国民经济中的比重, 是解决张掖市水资源危机的有效途径. 相似文献

Geothermal energy is a clean energy source that can potentially mitigate greenhouse gas emissions, as its use can lead to a lower mitigation cost. However, research on the economic impacts of the geothermal industry is scarce. This paper describes the effect of the geothermal industry, its economic input and output, using Beijing as a case study. This paper adopts the input–output model. The results show that the demand for and input use of the geothermal sector vary greatly across industrial sectors: electricity, heat production, the supply industry and general equipment manufacturing have the greatest direct consumption coefficient for the geothermal industry. When considering direct and indirect demand, it is clear that the geothermal industry has a great effect on different industrial sectors in diverse ways. Its influence coefficient and sensitivity coefficient are 1.2167 (ranked 11th) and 1.2293 (ranked 8th), respectively, revealing that it exerts obvious demand-pulling and supply-pushing effects on the regional economy. 相似文献

A growing literature on evolutionary economic geography concludes that regional industrial evolution is path-dependent and is determined by the preexisting industries. This study more accurately calculates the industry relatedness based on the co-occurrence approach to portray the production space of China’s manufacturing sectors and then examines the impact of industry relatedness on regional industrial evolution. The findings report that industry relatedness does underscore the regional structural change in China but shows significant regional differences in the evolution path. The coastal region has strong tendency of path dependence in its industrial evolution, while North West and South West break the path-dependent trajectory and transition into high productive sectors distant from their own production network. The results suggest that governmental policies can play a crucial role in creating new paths in the West. Institutions matter to allow the significant role of industry relatedness in driving regional industrial evolution. 相似文献
