摘　　要：利用信息熵对我国装备产业1987-2004年的时空分异状况进行了测度。计算结果表明,我国装备产业在不同地区、不同行业的演化速度和发展规模不尽相同,呈现出显著的时空分异特征。在时间序列上我国装备产业演化可以分为三个阶段,演化特征呈现"均衡→非均衡→均衡"格局。在空间布局上我国装备产业呈现较强的地理集中现象,且装备产业地理集中存在地方性行业垄断特征,不同行业集中趋势不同。研究认为:对于装备产业发展均衡性地区,宜形成独具特色的装备行业分工;对于目前装备产业产值份额较低的省市,由于外部环境、地理区位等因素制约,装备产业发展不具有总体竞争优势,应特别重视主导装备产业的培育。装备产业分工的地方化特征是导致装备产业布局与空间距离具有弱相关性的直接原因。装备产业在空间布局上应加强增长极的培育和发展,通过专业化分工,优化资源组合,从整体上提升我国装备产业的发展水平。The evolution situation in time and spatial series of Chinese equipment industry is measured by the information entropy. The conclusion indicates that the equipment industry evolution can be divided into three stages in the time series, the evolved characteristic presents ＂balance-unbalancebalance＂ pattern. Equipment industry of China takes on strong geography concentration phenomenon in the spatial distribution, at the meanwhile the industry geography concentration shows local profession monopoly characteristic. Further more the different industry concentration tendency is different. The results have shown： the balance area of the equipment industry development should form specialization division of labor. The provinces and cities of low output share of the equips industry should pay attention to cultivate the lead equipment industry specially, because the development of equipment industry does not hold competitive advantage in these area as a result of factor restrictions of the external environment, geography position and so on. The localization characteristic of distribution is the efficient causation, which leads to the weak relevant between the equipment industrial layout and the space length. We should cultivate the rising poles of equipment industry in the spatial layout. The development level of equipment industry will be upgraded by optimizing resources combination.
