• Non-squamous non-small cell lung cancer confirmed by histology or cytology (excluding sputum cytology), and according to the International Association for the Study of Lung Cancer (IASLC) eighth edition staging criteria, evaluated as stage IIIB-IV inoperable treatment or locally advanced, recurrent or metastatic subjects who cannot receive radical radiotherapy or refuse radical radiotherapy; if there are multiple tumor components, they should be classified according to their main cell types;
• EGFR, ALK, ROS-1 positive patients can be enrolled voluntarily, and the subjects need to provide the test results report of the above genes (If the subject fails to provide the EGFR, ALK, ROS-1 gene test report, he or she must provide tissue sections or tumor specimens for testing in this research center or a tertiary hospital. When the driver gene is unknown, the investigator and the subject jointly decide whether to join the group);
• At least one evaluable target lesion confirmed by imaging (evaluated according to RECIST 1.1 criteria);
• ECOG PS score is 0-1;
• Expected survival time ≥ 6 months;
• No systematic anti-tumor treatment for locally advanced or metastatic non-squamous non-small cell lung cancer [Subjects can be enrolled if they receive adjuvant therapy after completing curative treatment for early-stage non-small cell lung cancer, but have disease recurrence. In this case, the end time of adjuvant therapy is required to be more than 6 months after the first administration of this study, and the various toxic reactions caused by adjuvant therapy have recovered (judged by CTCAE 5.0 standard ≤ grade 1, except for alopecia ) or a new lesion appeared 6 months after the end of radical radiotherapy in stage IIIB patients]
• Laboratory results at screening:

Blood routine: white blood cell count≥3.5×109/L, absolute value of neutrophil ≥1.5×109/L, platelet count ≥100×109/L, hemoglobin ≥100g/L; Liver function: total bilirubin ≤1.5× upper limit of normal (ULN); subjects without liver metastases had alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5×ULN; liver Metastatic subjects with ALT and AST ≤ 5×ULN; Renal function: Serum creatinine ≤1.5×ULN or creatinine clearance ≥ 55mL/min, and urine routine test results show urine protein <2+, for subjects whose urine routine test shows urine protein ≥2+ at baseline, 24 hours urine collection should be performed and protein content in urine <1.0g within 24 hours; Coagulation function: International Normalized Ratio (INR) ≤1.5, and Activated Partial Thromboplastin Time (APTT) ≤1.5×ULN;

• Female subjects of childbearing age, male subjects and male subjects' partners agree to use reliable contraceptive measures from the time of signing the informed consent to 6 months after the end of the last trial drug infusion (such as abstinence, or physical contraception, or hormonal contraception, etc.);
• Subjects need to communicate well with the investigator, and be able to follow the visit, treatment, laboratory examination and other relevant regulations.

Exclusion Criteria:

• Malignant tumors other than lung cancer within 5 years, excluding cured cervical carcinoma in situ, skin basal cell or squamous cell skin cancer, local prostate cancer after radical resection, and breast ductal carcinoma in situ after radical resection, etc. ;
• Left ventricular ejection fraction (LVEF) < 50% by color Doppler echocardiography;
• Imaging examination at the screening stage show that the tumor approaches, surrounds, or invades the lumen of a large vessel (eg, the pulmonary artery or superior vena cava);
• Subjects with high suspicion of idiopathic pulmonary fibrosis, organizing pneumonia, drug-related pneumonia, idiopathic pneumonia, active pneumonia or active pulmonary tuberculosis by chest imaging examination during the screening stage;
• Previous history of hypertensive crisis, hypertensive encephalopathy; or uncontrolled hypertension (systolic blood pressure>150mmHg, and/or diastolic blood pressure>100mmHg);
• Any unstable systemic disease within 6 months prior to randomization: Including but not limited to cerebrovascular accident or transient ischemic attack, unstable angina pectoris, myocardial infarction, congestive heart failure [New York Heart Association (NYHA) grade ≥ grade II], severe arrhythmia requiring drug treatment, etc.;
• There are serious unhealed wounds or fractures, or major surgery (including thoracotomy, or major surgery is expected during the study period) within 28 days before randomization; For major surgery, refer to the 3rd and 4th grade surgery stipulated in the "Administrative Measures for the Classification of Surgery in Medical Institutions (Trial)";
• Subjects who have undergone minor surgery within 48 hours before randomization, and who are judged by the investigator to have a bleeding tendency;
• Subjects who have a history of chest radiotherapy within 28 days before randomization, or those who have received palliative radiotherapy for bone metastases within 14 days before randomization;
• History of the following within 6 months before randomization: peptic ulcer, gastrointestinal perforation, erosive esophagitis or gastritis, inflammatory bowel disease or diverticulitis, abdominal fistula, or intra-abdominal abscess;
• Definite diagnosis of tracheoesophageal fistula;
• Bleeding tendency, high bleeding risk, or coagulation disorder, including history of hemoptysis within 3 months before screening (single hemoptysis ≥ 2.5 ml bright red blood),or recently (≤10 days from first dose of study drug) full-dose oral or parenteral anticoagulants or thrombolytics or aspirin (>325 mg/day) or other non-steroidal anti-inflammatory drugs that inhibit platelet function; or have undergone surgery before, and the investigator judges that they have bleeding tendency;
