AN OPTION PERSPECTIVE ON GENERATING AND MAINTAINING PLANT VARIETY RIGHTS IN CHINA AgEcon
Koo, Bonwoo; Pardey, Philip G.; Qian, Keming; Zhang, Yi.
Notwithstanding the ambiguous research and productivity promoting effects of plant variety protections (PVPs), even in developed countries, many developing countries have adopted PVPs in the past few years, in part to comply with their Trade-Related Aspects of Intellectual Property Rights (TRIPS) obligations. Seeking and maintaining PVPs reserves options to an expected revenue stream from the future sale of protected varieties, the value of which varies for a host of reasons. In this paper we empirically examine the pattern of plant variety protection applications in China since its PVP laws were first introduced in 1997. We place those PVP rights in the context of China's present and likely future seed markets to identify the economic incentives and...

China's Domestic Agricultural Support Policy; Structure and Efficiency of Green Box Policy AgEcon
Qian, Keming.
The production function and multi-regional trade partial equilibrium model are applied to analyze China's domestic agricultural support policy,with the focus on structure and efficiency of Green Box policy.The major findings are: China's green box policy are targeted to increase productivity and secure food supply rather than to stabilize farmers' income or reduce the income gap. Investments on agricultural R&D and rural education,which have lower proportion and lower growth rate compared with the investment on rural infrastructure,have higher return in the terms of the marginal return and cost reduction. It is found that the externality of the impact of investments on R&D and education in rural area are the principal factors which result in...

National and International Agricultural Research and Poverty: Findings in the case of wheat in China AgEcon
Chan-Kang, Connie; Fan, Shenggen; Qian, Keming.
The objective of this paper is to assess the economic and poverty impact of wheat research in China and the contribution of CIMMYT. Our results show that wheat research conducted by China and CIMMYT contributed significantly to increases in wheat production in China. These research benefits amounted respectively to 1.1 billion and 6.1 billion US dollars (measured in 2000 constant price) in 1982 and 1998. These represent 11.9 to 22.7 percent of the total value of wheat production. The impact of CIMMYT breeding research through direct sowing or use as breeding material is not very significant in China. However, these results may mask important variations across provinces within China. Offspring of CIMMYT varieties are mostly planted in Southwestern and...

NATIONAL AND INTERNATIONAL AGRICULTURAL RESEARCH AND RURAL POVERTY: THE CASE OF RICE RESEARCH IN INDIA AND CHINA AgEcon
Fan, Shenggen; Chan-Kang, Connie; Qian, Keming; Krishnaiah, K..
The study attempts to measure the total benefits from rice varietal improvement research in China and India using variety adoption and performance data over the last two decades. It then uses genetic or pedigree information to partition the total benefits between these two countries and IRRI. Finally, the study uses reported elasticity of poverty reduction with respect to agricultural output growth to assess the effects of national and international research on poverty reduction in rural India and China. The results indicate that rice varietal improvement research has contributed tremendously to increase in rice production, accounting for 14-23 percent of total production value over the last two decades in both countries. Rice research has also helped...

The Role of Agribusiness Firms in Agricultural Research: The Case of China AgEcon
Zhang, Huijie; Fan, Shenggen; Qian, Keming.
Despite the efforts of various economists and agricultural scientists in calling for more investments, funding for agricultural R&D has been stagnated for the last two decades in China. This will pose a great challenge for the China's agricultural sector. Productivity has leveled off, and farmers' income has been flat. As a result, poverty reduction in recent years has also not shown any significant progress. On the other hand, agribusiness firms have emerged rapidly since the rural reforms initiated in 1978. Emerging of these firms has fundamentally changed the landscape of Chinese agricultural production. In 2003, they account for a significant share in agricultural GDP (7%), and agricultural employment. More importantly, it is their role in...
