产业内竞争、技术进步与增长收敛性测度——基于生态学视角

Intra Industry Competition, Technological Progress and Growth Convergence Measurement——Based on Ecological Perspective

摘要:

基于生态学原理,构建种群竞争模型。利用logistic模型测算研究样本的种群互动关系。选取全国总体以及浙江、江苏、上海、广东等发达地区的工业企业种群为研究样本。多数研究区域的工业企业处于种群协同状态。以全要素生产率指标表示技术进步。测算工业企业种群投入产出指标的Malmquist指数,得到技术进步、技术变化和效率变化的趋势。结果表明：2000年以来的经济高速增长过程中,技术变化对技术进步的贡献比较高。技术效率的贡献度不高。技术变化与技术进步有着相同的变化趋势。技术变化与技术进步的变化没有出现明显收敛。工业企业种群协同态势下技术进步明显,技术进步主要依赖技术变化,技术效率改进空间较大。

Abstract:

A population competition model is constructed based on the principle of ecology. The paper calculates the interaction of samples with logistic model. The industrial enterprises in the whole country area and developed regions such as Zhejiang, Jiangsu, Shanghai, Guangdong are taken as the sample. Most of the enterprises in the study area are in the state of population coordination. Technical progress was showed with total factor productivity. The Malmquist index of input and output index of industrial enterprises was calculated, and the trend of technical progress, technical change and efficiency was obtained. The results show that: in the rapid growth since 2000, the contribution of technological change to technological progress is relatively high. The contribution of technical efficiency is not high. Technological change and technological progress have the same change trend. There is no obvious convergence of technological change and technological progress. Technical progress is obvious in the situation of industrial enterprise population cooperation. Technological progress depends mainly on technological change. Technical efficiency has a larger space for improvement.
