劣势
1. 回顾文献做的不够,第一部分很唐突地回顾了埃及棉。
2. The part of 数据和实证模型 is not clear, for example, it didn't explain 资本和物质输入 include what respectively, and why we use 小时和吨 as units. Neither does the author treat all the province in Egyptas the research object, nor does him explain many province as the research sample. Just general give 171 samples; Variables in 表格1 shows that for every per hectare inputs, it is easier for the readers to understand the Egyptian cotton production situation; k,in line 184, is not found in the formula 11; think more about the formula derivation TE in formula 13.
3. The empirical analysis part did not fully explain to the empirical results.
4. In the part of 结论,The author mentioned that the novelty of this study is on the construction of the four models, but in fact these models are already very mature, and there are a lot of research results.
5. The expression of language is a bit lacking, and this paper has several non-standard language expression.
对作者的建议
1. In the part of 开头, author points out that the cotton production is very important in Egypt, but only gives some very broad reasons. it need the support of data.
2. It is suggested to replenish the existing literature focus on the agricultural total factor productivity research methods, research contents, research conclusion.
3. It is suggested to combine the 方法论 and 经验模型。Introduce the data individually.
4. In the part of 数据,it is suggested to explain more about variables
5. In the part of 结果, the author need to refer to the practical situation of Egyptian cotton industry to make a convincing explanation to the empirical results.It will make the readers understand the rationality of the results appearing in the Egyptian cotton industry. Like the coefficient of capital K is not significant in 图表2, the author need to explain further; In addition, the progress of agricultural technological is more on the input of materialized in the mechanical, chemical fertilizer, seeds, so the technological progress reflect the growth of capital, material, rather than the growth of TFP. As a result, the technological progress in this article is only for technology progress resulted from independent innovation in agricultural, and does not represent that other industry technology innovation promote the agricultural technological progress. Therefore, in this article, agricultural technological progress's contribution to the Egyptian cotton industry production may be underestimated , it should be mentioned in the article.
6. Suggestion is to consummate some map elements in 图形1, for example, increasing scale and orientation
