Plenary paper 2: Why is the agriculture of advanced Western economies still organized by family farms? Will this continue to be so in the future?
用家庭农场在组织和农业生产、家务及非农就业上的效率优势，解释其在工业化非社会主义国家的主导地位，并讨论未来变化对家庭农场的影响。
The dominance and persistency of family farms in industrialized nonsocialist countries can only be explained by the theory that farm households organize agricultural and household production, and also very often off-farm employment, efficiently. The organizational unity of farms and households in agriculture has to be seen as a consequence of limited economies of size relative to the size of the family‘s labour capacity. Economies of size are increasing as well as labour capacity due to labour saving technological innovations. Smaller than technically ’optimal‘ farm sizes are further to be explained by lower transaction costs of family farms vis-à-vis hired labour farms. Future changes of these determinants and their implications for family farming are discussed.
