While in some countries the rise of a selfemployed sector is seen as symptomatic of the failure of the formal wage sector, in China there is evidence, the self employed sector is healthy, growing and increasingly sophisticated …
Relatively capital intensive … growth rate of profits and capital stock exceed that of TVEs

Since 1980 … China has clearly begun the path of transformation …
But, with still only about 40 percent of population in urban areas … if it is to continue to be successful in developing … it needs to necessarily continue to move along this ruralurban transformation path …
![Page 14: China’ s Agriculture - Hitotsubashi Universitycei.ier.hit-u.ac.jp/Japanese/events/documents/towardmodern... · 31 35 26. 9 47. 6 ... Varietal Turnover in China’s Agriculture,](https://reader031.vdocument.in/reader031/viewer/2022022721/5c676bd209d3f2bb148ba36b/html5/thumbnails/14.jpg)
Necessary but not Sufficient • Shifting labor to off farm sector / shifting population from
rural to urban is necessary … key is job creation in cities in industrial/service sectors
• But not sufficient … – Need to make sure those who are left behind are taken care of … – Need to make sure those who do not get jobs off the farm are being
invested in … – So: process can continue … – And, so: there is stability …
• Here is where the Role of Agriculture comes in … the poorest are still in agriculture … Agriculture is going to provide a large part of the resources for the remaining rural households to make the transformation ..

Summary
• Some of the basic foundations of a supportive environment exist for continued rural growth:
– Technology for raising technical efficiency / expanding productivity
– Markets for raising allocative efficiency / gains from specialization
– Gains in Domestic / International Market Liberalization
