Abstract:

Industrial economy is leading urban economy. Input in industrial projects is a vital means to industrial economic development. With constraints from urban land utilization, to increase input/output efficiency of industrial projects is key to raise land utilization efficiency. This paper aims at the industrial projects with recent four-year’s land supply, designs investment intensity, average land output, average land profits, land utilization efficiency, investment construction period, payback and input/output ratio, studies the index marked values and project investment scales, industrial relationship, and presents approaches to input/output efficiency in industrial projects, beneficial to save land and transform economic development means.

Key words: industrial economy, land utilization, industrial projects, efficiency

摘要：

工业经济是城市经济的主导，工业项目的投入建设是工业经济发展的重要途径。在城市用地紧张的制约下，提高工业项目投入产出效率是提高土地利用效率的关键。本文以某市近4年供地投入建设的工业项目为研究对象，设计了投资强度、地均产出、地均收益、土地利用率、投资建设周期、投资回报率和投入产出率等7项指标，对指标特征值及其与项目投资规模、所属产业的关系进行分析，提出提高工业项目投入产出效率的措施，对于有效节约土地、转变经济发展方式起着积极作用。
