Grain Scale Management (GSM) is a crucial factor in ensuring national food security. However, in countries facing rigid resource constraints and complex land tenure relationships, the strategy of promoting large-scale grain management through land management rights transfer may not be sustainable. Therefore, based on the traditional agricultural division of labor theory, we analyze the mechanism and rationality of Agricultural Production Socialization Services (APSS) with scale characteristics to promote GSM and propose a new approach to GSM with empirical evidence from China.

In an agricultural society, the farmland is a major form of national wealth and an increase in farmland holding is a sign of wealth accumulation; whereas in an industrial society, the question of whether a rise in farmland holding also increases the wealth accumulation of farmers with the possible choice of being migrant workers is worth theoretical discussion and empirically testing. This article explores the issue of whether farmland tenancy affects household asset allocation in a rapid industrialization period.

Ensuring compliance with China’s “1.8 billion mu” (120 million hectares) cultivated land preservation policy is a fundamental goal of land policy. Northeast China has experienced significant cultivated land expansion due to rigorous compensation policies over the past two decades, resulting in sustainable increases in grain output. This research employs remote sensing data to examine the spatial–temporal pattern and vulnerability of newly increased cultivated land expansion in Northeast China and its potential impact on food security.
