| 1. | The theory needs further clarification of the inside mechanism and the perfection of structure change model
理论上有待于进一步弄清楚结构突变的内在机理，实际运用中结构突变模型有待进一步完善。 |
| 2. | Structure change can be classified into unit root related structure change and cointegration structure change . the main subject of this paper is the previous one
关于结构突变问题大致可以分为有关单位根的结构突变问题和协整的结构突变问题。 |
| 3. | Structure change is the most advanced subject of unit root theory and cointegration theory which represents one of the developing trends in macro - econometrica
事实上，结构突变问题和单位根及协整理论一起构成了宏观计量经济学的核心内容和前沿课题。 |
| 4. | Because of high intelligence of gmdh modeling , the location and the break kind of break - point can be determined automatically , then the optimal model can be obtained
由于gmdh建模的高度智能化,因此能够自动选择结构突变点的位置和突变类型,准确地得到最优的结构突变点。 |
| 5. | At present , though the theory is far from maturity and the empirical practice is limited , further study and research on the subject carry great significance
但是目前，结构突变问题在理论上尚未成熟，实证中运用也是很有限，尽管如此，对结构突变问题的进一步探讨和研究意义重大。 |
| 6. | Furthermore , selecting the criterion value of f incremental statistic may control the significance of the breaks in order to accommodate to variant investigation intentions
同时,由于f增量贡献统计量的使用,可以通过调整f增量贡献值来控制搜索的结构突变点的显著程度,以适应不同的研究目的。 |
| 7. | Structural change has become a more and more important area of econometrics research , as well as financial invenstmet area . but the literature addressing the issue is relatively scarce
对结构突变理论的研究不仅成为计量经济学领域一个越来越重要的研究方向,而且在金融投资领域有着重要的研究意义。 |
| 8. | Finally the author use his own new idea explain knotty questions appearing in the history and further analyze and explain the economic reasons causing the structure change in stock index
随后运用笔者新的提法解释了历史上出现的疑难问题，最后也依笔者的思路分析并解释了上证指数结构突变的经济原因。 |
| 9. | The research of unit root related structure change abroad took place mainly in america in 1990s , which included the so - called " perron phenomena " and " partly anti - perron phenomena "
本文主要研究的是前者。国外，有关单位根的结构突变研究主要集中在90年代的美国，即所谓“ perron现象”和“部分逆perron现象”等。 |
| 10. | The result indicates that the dgp of energy demand of china is trend stabilization with a structural break , and the energy demand of china will increase reposefully with statuesque increase route determinately
我们的研究表明，中国能源需求的数据生成过程是带有结构突变的趋势稳定过程，这说明中国能源需求将会沿着确定的均衡增长路径平稳增长。 |
