The complicated legal status of land properties in Poland connected with some of them lacking clearly defined development conditions leads to investors taking risks when purchasing land for investments, who often hope to pay a lower than average market price for such a real estate. The aim of the article is an attempt to assess planning conditions risk taken by investors by the analysis of transaction prices of land properties. In this context, the research question of whether the lack of clearly defined development conditions for land carries over onto lower prices of land plots purchased by investors was posed. This is a reference to studies carried out in the years 2008–2015. Conducted in the article will be a comparative analysis of land property prices from areas characterized by with varying planning conditions. The analyses make use of causal models with a single dependent variable – accounting for differences in (un)defined development conditions. The carried out analysis for areas of two communes from the suburban zone of the city of Bydgoszcz showed that the buyers of real estate perceive a difference in the planning conditions of the purchased building plots. Those which have clearly defined development conditions are attributed with higher values. Land without defined development conditions, in Poland under only a study of conditions and directions of spatial development, are attributed with lower values. Recognizing the above relationships is necessary when taking investment decisions and making proper assumptions in the land property valuation procedure.

以波兰城市郊区为例，规划条件风险下的土地财产价值


波兰土地财产的法律地位复杂，其中一些缺乏明确的开发条件，导致投资者在购买土地进行投资时承担风险，他们往往希望以低于平均市场价格的价格购买此类房地产。本文的目的是试图通过分析土地产权的交易价格来评估投资者所承担的规划条件风险。在此背景下，提出了以下研究问题：缺乏明确的土地开发条件是否会影响投资者购买地块的较低价格。这是 2008 年至 2015 年进行的研究的参考。本文将对具有不同规划条件的地区的土地价格进行比较分析。这些分析利用具有单个因变量的因果模型——考虑（未）定义的开发条件的差异。对比得哥什市郊区两个公社地区进行的分析表明，房地产买家认为所购买建筑地块的规划条件存在差异。具有明确发展条件的，具有较高的价值。在波兰，没有明确开发条件的土地仅根据空间开发的条件和方向进行研究，其价值较低。在做出投资决策并在土地财产评估程序中做出适当假设时，必须认识到上述关系。
