26 pages, Agricultural productive services are an important means to achieve effective allocation of regional resources and play an important role in ensuring food security and improving farmers’ welfare. However, the development process of agricultural productive services still faces problems such as large differences in service levels in different segments and low participation rates in the full service. In order to investigate the influential paths of the low participation rate of farmers in the full-service process, this study takes maize farmers in northeast China as the research object. Based on 937 survey data from six cities in three northeastern provinces, we used the Item Response Theory (IRT) model to measure farmers’ information acquisition ability and constructed the Heckman two-stage model and the IV-Heckman model to analyze the logical framework of “information acquisition ability—farmers’ choice of productive agricultural services”. The main findings are as follows: firstly, the more channels there are, the stronger the farmers’ channel internalities; the higher the degree of channel differentiation, the stronger the farmers’ channel internalities. Second, after addressing the sample selection bias and endogeneity, there is a small rise in the facilitation effect of information acquisition ability on farmers’ productive agricultural service behavior. Third, this facilitation effect is achieved through farmers’ perceived usefulness of productive agricultural services, and the mediating effect of perceived ease of use is not significant. Therefore, fostering farmers’ self-perceptions and optimizing information delivery strategies are effective ways to promote farmers’ choice of agricultural productive services and to facilitate the modernization of Chinese agriculture. In general, this study helps to reveal the theoretical mechanism of farmers’ information asymmetry, and provides empirical evidence for how to promote the development of agricultural productive services.
11 pages, via online journal, Land fragmentation is an interesting physical character in some developing countries, especially China. This study aims to discover the direct and mediated effects of land fragmentation on collective action in China based on an empirical test and the social-ecological system framework. We introduce three innovations to the literature on collective action in the commons. First, we focus on the mechanism of land fragmentation on collective action in the commons, which has been largely ignored in the literature. Second, building on the social-ecological system framework, we use structural equation modeling, which is robust to endogeneity and latent variable problems. Third, we use original survey data from 3895 households and 284 villages from 17 provinces/regions in China, a critical case because China has some of the most fragmented farmland use in the world. We find that land fragmentation has a direct negative effect on irrigation collective action. And besides the direct negative effect, there are four indirect factors: dependency on farming, irrigation rule-making, economic pressure and land circulation. Of these, the first three have a negative effect, and the last one, a positive effect. Our findings add to the theoretical literature on collective action in the commons and suggest new policy handles for more efficient land and labor markets in China.

This paper describes the present status and development of the Chinese agricultural documentation and information systems and the core role of the National AGRIS Center played in promoting the development of the systems. The emphasis has been placed in coordinating and establishing the agricultural databases, computer searching systems, information transmitting systems and international cooperations in China. It points out that the common strategic task facing all the developing countries in the establishment of national agricultural databases in each country and selectively contribute the valuable data to the international agricultural databases for information resources sharing of the world. Digitizing of Chinese characters for establishing the Chinese agricultural databases, the techniques of development and use in dealing the Chinese charactes as well as the technical line adopted for the construction of the Chinses agricultural databases have been also disucssed.
