| This paper examines the relationship between farm size and productivity in China's agriculture. In developing agriculture where there is a broad range of farm sizes, farm size and productivity or output per unit of land are often found to be inversely related. In China, where average farm size is small and the distribution of farm sizes is relatively compact, farm size and productivity are weakly inversely related. However, when we utilize the egalitarian principle during land allocation in China and use imputed homogenous land area rather than actual land area in the regression, the inverse relationship between farm size and productivity disappears. Hence, the strong inverse relationship that some studies have found are undoubtly due to a number of... |

| Although health is an important factor in economic development, millions of China's rural residents have no medical coverage. Nearly 10 percent of those that were sick in rural China consciously did not seek medical care, mostly because of financial constraints. More than 25% of rural residents are dissatisfied with their village's health system. In response to this deteriorating situation, a new cooperative medical system (NCMS) was initialized in rural China in 2003 by the government. However, after two years of trials, there has been no household-based, economic analysis of the program. This paper provides one of the first. Although where introduced, most rural residents voluntarily participate, there are many problems with the program. First, at least... |

| This paper aids researchers who are conducting microeconomic work in developing countries to more effectively collect farm production data. The discussion focuses on helping the researcher who has fairly well-defined research ideas to better visualize the steps that are necessary for collecting farm production data by raising conceptual and organizational issues that will be faced during the collection process. A wide range of data collection strategies is reviewed for both data-intensive studies that concentrate on production and technological issues, as well as less intensive studies that are only interested in measuring the contribution of farming activities to overall household income. Both survey-based and recordkeeping methodologies are discussed and... |

| This paper uses household data from Northeast China to examine the link between investment and land tenure insecurity induced by China's system of village-level land reallocation. We quantify expropriation risk using a hazard analysis of individual plot tenures and incorporate the predicted hazards of expropriation into an empirical analysis of plot-level investment. Our focus is on organic fertilizer use, which has long lasting benefits for soil quality. Although we find that higher expropriation risk significantly reduces application of organic fertilizer, a welfare analysis shows that guaranteeing land tenure in this part of China would yield only minimal efficiency gains. |

| The overall goal of our paper is to understand the impact that irrigation investments in China have had on incomes, in general, and income and poverty alleviation in poor areas, in particular. The paper seeks to meet three objectives. First, we describe the relationship among irrigation status, crop choice, yields and household crop revenue. Second, we seek to understand the magnitude and nature of the effect that irrigation has on yields and crop revenue. Finally, we seek to understand the impact that irrigation has on incomes in poor areas. Our analysis shows that irrigation contributes to increases in yields for almost all crops and in income for farmers in all areas. The importance of cropping income in poor areas and the strong relationship... |

| This article examines technical efficiency of the Chinese grain sector using the framework of stochastic production frontier. The results reveal that: the marginal products of labor and fertilizer are much smaller than that of land; human capital and farm-level specialization have positive effect on efficiency, land fragmentation is detrimental to efficiency, and elder farmers are as efficient as younger farmers. We also examine the effects of size, mechanization and geographic location. Simulation results show that significant output gains can be obtained by eliminating land fragmentation, improving rural education and promoting specialization and mechanization. |

| With rapid income growth, dairy production and consumption in China have increased significantly. This emergence of the dairy sector will provide opportunities for farmers to participate in a high-value, potentially more lucrative enterprise. The overall goal of this paper is to analyze the major determinants of farmers’ participation in dairy production. Our main question is whether or not the pace of the emergence of the dairy processing industry has affected the ability of farmers to participate in dairy production and whether or not it has limited the expansion of their herd size. Based on household, village and processor surveys conducted in the Greater Beijing region, our analysis shows that the location of dairy processing firms is one of the key... |

| In urban China the Household Income and Expenditure Survey requires respondents to keep a daily expenditure diary for a full 12-month period. This onerous reporting task makes it difficult to recruit households into the survey, compromising the representative nature of the sample. In this article we use data on the monthly expenditures of households from two urban areas of China to see if data collection short-cuts, such as extrapolating to annual totals from expenditure reports in only some months of the year, would harm the accuracy of annual expenditure, inequality and poverty estimates. Our results show that replacing 12-month diaries with simple extrapolations from either one, two, four or six months would cause a sharp increase in estimates of annual... |

| The overall objectives of our proposed paper is to: (a) systematically document the post-reform trends in agricultural performance in Asia, Europe, and the Former Soviet Union; (b) identify the main reform strategies and institutional innovations that have contributed to the successes and failures of the sector; (c) analyze the mechanisms by which reform policies and initial conditions have affected the transition process in agriculture; and (d) draw lessons and policy implications from the experiment and identify the gaps in our understanding of the role and performance of agriculture in transition. As part of this effort, we attempt to address a number of intriguing and important questions on the performance of individual countries or regions during... |

| The supermarket revolution has arrived in China and is spreading as fast as or faster than anywhere in the world. As the demand for vegetables, fruit, nuts and other high valued products have risen, urban retailers are finding new venues seized on niche and today have over $55 billion in sales, more than a third of the urban food market. However, the experience of many developing countries suggests that there could be serious distributional impacts of the rising of supermarkets. There is concern among policy makers and academics that poor, small farmers might be excluded from market. The main goal of our paper is to understand what types of farmers have been able to participate in the horticultural revolution, how they interact with markets and how... |

| Poverty maps provide information on the spatial distribution of welfare and can predict poverty levels for small geographic units like counties and townships. Typically regression methods are used to estimate coefficients from the detailed information in household surveys, which are then applied to the more extensive coverage of a census. One problem with standard regression techniques is that they do not take into account the ‗spatial dependencies‘ that often exist in the data. Ignoring spatial autocorrelation in the regression providing the coefficient estimates could lead to misleading predictions of poverty, and estimates of standard errors. Household survey data usually lack exact measures of location so it is not possible to fully account for this... |

| Inefficient performance of irrigation systems not only leads to a waste of water resources, but may also affect agriculture production, especially in regions facing a water stress problem. In rural China, only 40% of the water allocated to irrigation is effectively used, a figure much lower than many developed countries (Wang, 2000). Although traditional irrigation technology such as flood irrigation accounts for part of the inefficient use of water, the lack of effort in managing surface irrigation systems are also thought to affect the performance of China's water systems (Wang et al., 2003). In confronting problems with China's irrigation systems, leaders have begun experimenting with changing the institutions that manage water in rural communities.... |

| The overall aim of the present paper is to better understand the evolution of tubewell ownership in the North China Plain, especially focusing on the factors that determine ownership and its effect on production. Based on a random sample of 30 villages in three counties in the Hai River Basin, our results show that collectively owned tubewells have been gradually privatised. The analyses demonstrate that increasing water and land scarcity and policy intervention (mainly fiscal and financial subsidies for tubewell investment) leads to the observed shifts in tubewell ownership patterns. The results also show that the privatisation of tubewells has affected cropping patterns in the North China Plain. When villages shift towards private tubewells, farmers move... |
