Table 1 Model variables and quantitative criteria.
From: Batch evaluation of collective owned commercialised construction land using machine learning
Factors | Variable | Variable description |
|---|---|---|
Social economy | Township per capita net income (X1) | Annual per capita net income of the township where the land is traded |
Arable land per capita (X2) | The per capita cultivated land area of the township where the transaction land is located, unit mu/person | |
Population density (X3) | Population density of the township where the transaction land is located | |
Location | Prosperity (X4) | The straight-line distance between township government and municipal government, unit: km |
Road Accessibility (X5) | The highest score for road types passing through township governments is 6 points for national roads, 5 points for highway entrances, 4 points for provincial roads, 3 points for county roads, 2 points for township roads, and 1 point for village roads | |
External transportation convenience (X6) | Number of long-distance lines between towns and cities and other towns, 1 point for each line, 5 points for five or more lines | |
Infrastructure perfection (X7) | Township infrastructure: water, electricity, roads, communication, ventilation, each item 1 points, up to 5 points | |

Individual | Area (X9) | Transaction land area, unit: mu |
Plot ratio of development planning (X10) | The ratio of gross floor area to net site area of the transaction lot | |
Development Planning Building Density (X11) | The ratio of the sum of the base area of the building in the transaction plot to the occupied land area | |
Market Access (X12) | The method by which a transaction parcel enters the market is scored based on the transaction costs associated with that parcel. Higher scores correspond to higher costs, with adjusted market entry assigned 4 points, consolidated market entry 3 points, on-site market entry 2 points, and market entry after agricultural land conversion approval 1 point | |
Planned Market Use (X13) | The land use of the trading land after entering the market is assigned points according to the expected economic income of the land after entering the market.
