Abstract: The ambiguity of China’s farmland ownership is a deep-seated problem. By classifying the ambiguous property rights and unfolding the concept of rent dissipation, this paper tries to analyze such key issues as the vague changes and property right performance of China’s farmland ambiguous property rights, the institutional diversity, and market-oriented reform, etc.. The results show that the internal structure of China’s farmland ambiguous property rights presents different characteristics at different historical period. At the beginning of reform, the huge improvement of the performance of farmland property results from the decrease of losses in farmland ownership rent dissipation in terms of production efficiency, while the reduction of farmland property efficiency afterwards is mainly due to losses of property rent dissipation in terms of allocation efficiency. Meanwhile, the appearing and tests of diverse farmland systems, under the gradually eased farmland property rights control by the state, are often shown as the expression and combination of different bundles of rights in grabbing non-proprietary rental value of farmland by each principal body. Besides, the inter-government behaviors could have some implications of learning, imitation and competition towards the diversity of farmland property right system. The direction and degree of farmland rent sharing can decide the direction of the changes of farmland property right system.

Key words: ambiguous farmland property rights; rent dissipation; performance; institutional changes
