Moreover, a reasonable monetary policy improves the efficiency of financial operations on a global scale and effectively resolves the financial crisis. At present, scholars from various countries have begun to pay attention to the issue of differentiated formulation of monetary policy among regions. This paper combines machine learning to construct a monetary policy differentiation effect analysis model based on the GVAR model. Moreover, this paper uses the gray correlation analysis method to obtain the gray correlation matrix between industries, and then introduces the industry\u2019s own characteristics, industry relevance and macroeconomic factors into the macro stress test of credit risk. In addition, this paper constructs a conduction model based on the industry GVAR model, and uses the first-order difference sequence of GDP growth rate, CPI growth rate and M2 growth rate of each economic region to construct a GVAR model to test the impulse response function. The results of the test show that the monetary policy shocks of various economic regions are significantly different. All in all, the research results show that the performance of the model constructed in this paper is good.<\/jats:p>","DOI":"10.3233\/jifs-189494","type":"journal-article","created":{"date-parts":[[2020,12,11]],"date-time":"2020-12-11T12:43:31Z","timestamp":1607690611000},"page":"6567-6579","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Regional effect of monetary policy based on GVAR model and machine learning"],"prefix":"10.1177","volume":"40","author":[{"given":"Zengming","family":"Zhao","sequence":"first","affiliation":[{"name":"Henan Police College, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenting","family":"Chen","sequence":"additional","affiliation":[{"name":"Henan Finance University, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,12,8]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1257\/aer.20160042"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1257\/aer.20160137"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.3982\/ECTA10104"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfineco.2014.11.001"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1257\/aer.104.3.721"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/qje\/qjx019"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/infi.12104"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1353\/eca.2017.0004"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/jmcb.12134"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.1093\/rof\/rfu035"},{"key":"e_1_3_1_12_2","doi-asserted-by":"publisher","DOI":"10.1257\/aer.110.4.943"},{"key":"e_1_3_1_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/1468-0327.12042"},{"issue":"96","key":"e_1_3_1_14_2","first-page":"531","article-title":"Monetary policy and bank profitability in a low interest rate environment","volume":"33","author":"Altavilla C.","year":"2018","unstructured":"AltavillaC., BoucinhaM. and Peydr\u00f3J.L., Monetary policy and bank profitability in a low interest rate environment, Economic Policy 33(96) (2018), 531\u2013586.","journal-title":"Economic Policy"},{"issue":"2","key":"e_1_3_1_15_2","first-page":"853","article-title":"Signalling effects of monetary policy","volume":"84","author":"Melosi L.","year":"2017","unstructured":"MelosiL., Signalling effects of monetary policy, The Review of Economic Studies 84(2) (2017), 853\u2013884.","journal-title":"The Review of Economic Studies"},{"key":"e_1_3_1_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/jmcb.12119"},{"key":"e_1_3_1_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.red.2014.11.002"},{"key":"e_1_3_1_18_2","doi-asserted-by":"publisher","DOI":"10.1111\/jmcb.12338"},{"key":"e_1_3_1_19_2","doi-asserted-by":"publisher","DOI":"10.1057\/imfer.2016.4"},{"key":"e_1_3_1_20_2","doi-asserted-by":"publisher","DOI":"10.1257\/mac.20130237"},{"key":"e_1_3_1_21_2","doi-asserted-by":"publisher","DOI":"10.1257\/aer.20171400"},{"key":"e_1_3_1_22_2","doi-asserted-by":"publisher","DOI":"10.1257\/mac.20150016"},{"key":"e_1_3_1_23_2","doi-asserted-by":"publisher","DOI":"10.1257\/mac.20140003"},{"key":"e_1_3_1_24_2","doi-asserted-by":"publisher","DOI":"10.1057\/imfer.2016.5"}],"container-title":["Journal of Intelligent &amp; Fuzzy Systems"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/JIFS-189494","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.3233\/JIFS-189494","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/JIFS-189494","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T09:40:49Z","timestamp":1777455649000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/JIFS-189494"}},"subtitle":[],"editor":[{"given":"Varatharajan","family":"Ramachandran","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2020,12,8]]},"references-count":23,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2021,4,12]]}},"alternative-id":["10.3233\/JIFS-189494"],"URL":"https:\/\/doi.org\/10.3233\/jifs-189494","relation":{},"ISSN":["1064-1246","1875-8967"],"issn-type":[{"value":"1064-1246","type":"print"},{"value":"1875-8967","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,12,8]]}}}
