Research On Value Assessment Of Collectively-owned Commercial Construction Land Based On Improved Market Method

The newly revised "Land Administration Law" was officially implemented in January 2020.Article 63 of the Law stipulates that nationwide,collectivelyowned commercial construction land can be directly transferred to the market without land expropriation.This shows that its entry into the market will move from a local pilot reform to a national exploration.The nationwide market entry reforms urgently need to standardize and apply valuation methods to guide market entry transactions.However,through the analysis of the existing literature,it is found that there is still a big practical difference between entering the market in the legal sense and the practice reform of entering the market.In the process of evaluating the value of collectively-owned commercial construction land,in view of the imperfect development of the current collective-owned land transaction market in my country,the application of the market method mainly includes the small number of transactional cases of collectively-owned commercial construction land,the insufficient performance of land value,and the irregularity of the cases.There are practical difficulties such as lack of comparability between them.In view of this,it is necessary to take into account the specific characteristics of collectively-owned commercial construction land,fully consider its unique influencing factors of land prices,and further improve the market-based assessment process of collectively-owned commercial construction land by scientifically and reasonably learning from the evaluation model of stateowned construction land.In view of the above problems,on the basis of a large number of literature analysis and research,the circulation policy and the property of ownership are regarded as its special land price influencing factors,the land price evaluation index of collectively-owned commercial construction land is established,and the application of grey relational analysis to improve the market method is analyzed.By using the grey relational analysis method to build a model of the improved market method,by calculating the correlation coefficient between the objects,the degree of correlation between each transaction instance and the case study object is obtained,and the selection of comparable transaction instances is optimized,and by quantifying various factors The degree of influence on the collectivelyowned commercial construction land price,the adjustment factor correction process,and finally,in the land price correction step,corrections are made to different extents according to the degree of correlation,and the land price of collectively-owned commercial construction land is obtained.After the valuation model is established,this paper takes a collective commercial construction land in Longxi County,Gansu Province as the case analysis object,establishes the valuation model of the parcel based on the grey relational analysis and improved market method,and calculates the case under the improved market method.the value of the object.The research results show that:(1)Grey relational analysis can effectively improve the selection process of comparable transaction cases in the market method;(2)Grey relational analysis can reduce the subjectivity in the process of factor correction;(3)The improved market method based on grey relational analysis can improve collective The accuracy of the evaluation of the value of commercial construction land is closer to the actual transaction price.Therefore,grey relational analysis can effectively improve the process of evaluating collectively-owned commercial construction land by market method,making the evaluation process of collectively-operating construction land more standardized and the evaluation results more reasonable.
