代写论文：农业生产率
已有研究以地域划分（Fan＆Pardey，1997; Chen et al。，2008; Li＆Zhang，2013）或将时间缩短到几个较短的时间（Monchunk等，2010; Piese等。，2011）而不是一个时期。
不同作者关于农业增长的共同结果主要取决于技术进步（Chen et al，2008; Li＆Zhang，2013），其增长速度甚至超过了产量的增长速度。但是技术效率依然不变。这部分抵消了技术增长的影响（Chen，et al。，2008; Li＆Zhang，2013）。
Coyle等（1998），Chen等（2008）和Li＆Zhang（2013）将农业生产率的时间分为几个部分，也发现了农业全要素生产率增长的明显波动，这并不表现为产出的增长。国外研究表明，这些波动是由行业改革引起的，这意味着经济发生结构性变化。通过长期的论证，大多数文章都显示出该体系的加速发展，这可能是对公开市场体系的反应（Fan＆Pardey，1997; Coyle等，1998; Kanwar，2000; Chen，et al。 。，2008; Piesse等人，2011）。
因此，上述讨论表明，中国的主要问题是技术水平和生产力相对较低，缺乏开放的市场导向政策。近来，保护主义和国际因素的水平将比以前更加重要。
但是，静态模型并不能很好地解释从自给自足向全球合作市场的转变。要证明农业的全球化提高了中国的福利水平，需要从1960年到2010年的时间序列数据分析，这个时间序列数据分析可能包含中国自给自足和全球化的结构。

There have been researches which divide the country by regions (Fan & Pardey, 1997; Chen et al, 2008; Li & Zhang, 2013) or cut the time into several shorter length (Monchunk, et al., 2010; Piese, et al., 2011) instead of one period only.
A common result from different authors about the agriculture growth is significantly dependent on the technology improvement (Chen et al, 2008; Li & Zhang, 2013), which grows even faster than the growth rate of output. However it still has a constant low technical efficiency. It partially offsets the effect of technology growth (Chen, et al., 2008; Li & Zhang, 2013).
By dividing the time period into several parts, Coyle et al (1998), Chen et al (2008), and Li & Zhang (2013) also discovered obvious fluctuations in the TFP growth of agriculture, which is not shown by the growth of output. Researches abroad show that these fluctuations are caused by the reform of the industry, implying that there takes place a structural change in the economy. Through a long period’s testimony, most of the articles demonstrate an accelerated development in the system which could be the responses to the open market system(Fan & Pardey, 1997; Coyle, et al., 1998; Kanwar, 2000; Chen, et al., 2008; Piesse, et al., 2011).
Thus, the above discussion shows that the major issues with China are relatively lower technology level and productivity and lack of open market oriented policy. In the recent times, the level of protectionism and international factors will be much more important than before.
However, a static model does not render a good explanation to the change from self-sufficiency to global cooperation market. To prove the globalization of agriculture improves the welfare in China will need a time series data analysis from 1960 to 2010, which could contain both autarky and globalized structure in China.
